DETAILED DESCRIPTION


Sparassia crispa as used herein refers to a fruiting body of the Sparassia crispa. The fruiting body has a milky white to yellow appearance, and presents a flat and curly leaf-like structure.


In some embodiments, Sparassia crispa used for extraction of a Sparassia crispa extract may be fresh, dried, or frozen. In some embodiments, drying may be air drying, sun drying, drying in shade, or freeze drying.


In some embodiments, Sparassia crispa used for extraction of a Sparassia crispa extract may be intact Sparassia crispa or Sparassia crispa obtained after physical processing procedures such as chopping, dicing, slicing, milling, grinding, or otherwise that alter the size and physical integrity of raw materials.


In some embodiments, the Sparassia crispa extract is a liquid extract prepared by a water extraction step. In the water extraction step, extraction is performed at a specific temperature for a specific time using water as a solvent to prepare the Sparassia crispa liquid extract. In some embodiments, the specific temperature refers to a temperature between 95° C. and 85° C. In some embodiments, the specific temperature is 90° C.±5° C. In some embodiments, the specific temperature is 90° C. In some embodiments, the specific time refers to 60 min to 80 min. In some embodiments, the specific time refers to 60 min.


In some embodiments, the water extraction step further includes measuring Degrees Brix (°Bx) of the Sparassia crispa liquid extract after a specific time, and preparing the Sparassia crispa liquid extract when the Degrees Brix reaches 2.9°Bx±0.5°Bx. In some embodiments, the water extraction step further includes measuring Degrees Brix of the Sparassia crispa liquid extract after a specific time, and extending the specific time for another 30 min when the measured Degrees Brix does not reach 2.4°Bx. This means that the Sparassia crispa liquid extract is prepared with the Degrees Brix of 2.9°Bx±0.5°Bx as an acceptance standard. In some embodiments, the Sparassia crispa liquid extract is a Sparassia crispa extract.


In some embodiments, in the water extraction step, the weight ratio of the water to the Sparassia crispa is (15 to 5):1. By way of examples, the weight ratio of the water to the Sparassia crispa is 10:1. Here, if there is too little solvent or the specific time is too short, the extraction efficiency will significantly decrease. If the specific time is too long, active ingredients in the extract may be degraded.


In some embodiments, the Sparassia crispa extract is a Sparassia crispa liquid extract prepared by a water extraction step and a filtration step. The filtration step refers to a step of filtering the Sparassia crispa extract after the water extraction step through a sieve or centrifugation to remove solid matter in the Sparassia crispa extract. By way of examples, the Sparassia crispa extract is filtered through a 400-mesh sieve to prepare the Sparassia crispa liquid extract.


In some embodiments, the Sparassia crispa extract is a Sparassia crispa liquid extract prepared by a water extraction step, a filtration step and a concentration step. The concentration step refers to the step of removing excess water from the Sparassia crispa extract after the water extraction step or water extraction step and the filtration step to reduce the storage volume of the Sparassia crispa extract. By way of examples, concentration under reduced pressure can be performed at 60° C.±5° C. using a concentrator (brand/model: BUCHI-Rotavapor R-100), and is stopped until Degrees Brix of a solution is 10±0.5 to prepare a Sparassia crispa liquid extract. In some other embodiments, the concentration under reduced pressure can be performed at 50° C. to 82° C.


In some embodiments, the Sparassia crispa extract is used for preparing a composition for reducing light sleep and/or dreaming. In some embodiments, the Sparassia crispa extract is used for increasing gamma-aminobutyric acid (GABA) content. In some embodiments, the Sparassia crispa extract contributes to nerve relaxation.


In some embodiments, the present disclosure provides use of a Sparassia crispa extract, which is used for preparing a composition for increasing mitochondrial expression, where the Sparassia crispa extract is extracted from Sparassia crispa using water as a solvent. In some embodiments, the Sparassia crispa extract is used for enhancing activity of mitochondria in a cell. In some embodiments, the Sparassia crispa extract is used for extending a cell lifespan. In some embodiments, the Sparassia crispa extract is used for regulating autophagy of mitochondria in a cell. In some embodiments, the Sparassia crispa extract is used for regulating an expression level of a mitochondrial expression-related gene in human cells, and the mitochondrial expression-related gene is at least one of: a CCT5 gene, a CCT7 gene, a Pink1 gene, a Parkin gene, an SIRT1 gene, an FOXO gene, a PARP1 gene, and an SOD3 gene.


In some embodiments, the Sparassia crispa extract is used for preparing a composition for repairing cell damage, where the Sparassia crispa extract is extracted from Sparassia crispa using water as a solvent. In some embodiments, the Sparassia crispa extract is used for regulating autophagy of a cell. In some embodiments, the Sparassia crispa extract is used for enhancing an expression level of an ATG1 gene and/or an ATG8 gene.


In some embodiments, the Sparassia crispa extract is used preparing a composition for firming skin of a subject. In some embodiments, the Sparassia crispa extract is used for reducing laxity of the skin of the subject. In some embodiments, the Sparassia crispa extract is used for reducing dryness of the skin of the subject.


In some embodiments, the Sparassia crispa extract is used for enhancing activity of mitochondria in skin cells. Here, the mitochondria are an energy manufacturing factory of cells. The activity of the mitochondria will be reduced by the fact that the mitochondria are damaged by an external environment or degrade naturally, while diabetes, heart disease, arthritis and the like are also found to be related to a variation of mitochondrial DNA. For example, if the skin is irradiated by UV light for a long time, the mitochondrial DNA will mutate to reduce the activity of the mitochondria. If the activity of the mitochondria can be promoted, the metabolic rate and growth rate of the cell can be increased, and then the skin is repaired. From external observation, it can be seen that skin aging is slowed down. Furthermore, there are a large number of mitochondria in the brain. If the function of the mitochondria can be maintained normally, the smooth operation of the brain can be maintained, thereby avoiding insomnia caused by brain degeneration.


In some embodiments, the Sparassia crispa extract is used for regulating an expression level of a mitochondria-related gene to improve mitochondrial expression. In some embodiments, the mitochondria-related gene is at least one of: a CCT5 gene (Gene ID: 22948), a CCT7 gene (Gene ID: 10574), a Pink1 gene (Gene ID: 65018), a Parkin gene (Gene ID: 5071), an SIRT1 gene (Gene ID: 23411), an FOXO gene (Gene ID: 2308), a PARP1 gene, and an SOD3 gene (Gene ID: 6649).


In some embodiments, the Sparassia crispa extract is used for regulating an expression level of a cell autophagy-related gene to repair cell damage. In some embodiments, the cell autophagy-related gene is at least one of an Atg1 gene (Gene ID: 8408) and an Atg8 gene (Gene ID: 11345).


The CCT5 gene and the CCT7 gene regulate a mitochondrial activity-related gene. The Pink1 gene and the Parkin gene regulate a mitochondrial expression and degradation-related gene. This means that an energy source of a cell can be activated and aging of the cell can be delayed by promoting the expression levels of the CCT5 gene, the CCT7 gene, the Pink1 gene, and the Parkin gene.


The ATG1 gene and the ATG8 gene are involved in the autophagy of the cell, and metabolizing old waste organelles, and recycling recyclable substances by regulating the autophagy of the cell. This means that cell repairing capacity can be enhanced by promoting the expression levels of the ATG1 gene and the ATG8 gene.


When the PARP1 gene is expressed, NAD+ will be inhibited, thereby reducing mitochondrial activity, and influencing cellular energy. This means that the mitochondrial activity can be enhanced by inhibiting the expression level of the PARP1 gene. The SIRT1 (sirtuin) gene is to enhance the capacity of the cell to balance oxidative stress by promoting the mitochondrial activity. The FOXO gene is regulated by the SIRT1 gene, which in turn controls the expression of SOD3 gene. The SOD3 gene is regulated by the FOXO gene, which in turn influences extension of a cell lifespan.

Example 1: Preparation of Sparassia crispa Extract

Firstly, dried fruiting bodies of Sparassia crispa produced in a high-altitude fir forest zone in China were used as a raw material.


Next, a water extraction step was carried out. Using water as a solvent, the water was heated to 90° C.±5° C. (i.e., specific temperature), and then, the raw material of the Sparassia crispa was added. The Sparassia crispa raw material and the water were mixed in a weight ratio of 1:10. This means that after the Sparassia crispa was mixed with the water, extraction was performed at 90° C.±5° C. for 60 min (i.e., specific time) to obtain a Sparassia crispa liquid extract.


Subsequently, a filtration step was carried out. After being cooled to room temperature, the Sparassia crispa liquid extract was sieved through a 400-mesh sieve, and then its filtrate was taken.


Afterwards, a concentration step was carried out. The above-mentioned filtrate was taken and was subjected to concentration under reduced pressure at a set temperature of 60° C.±5° C. using a concentrator (brand/model: BUCHI-Rotavapor R-100), and the concentration was stopped until Degrees Brix of a solution was 10±0.5 to obtain a concentrate, i.e., a Sparassia crispa extract.


Example 2: Test of Sparassia crispa Extract to Promote Secretion of GABA

GABA has a full name of gamma-aminobutyric acid. When we enter deep sleep, GABA content of brain nerve cells will be increased. Stabilization of the GABA content of the brain also helps fight depression and help sleep. However, due to a blood-brain barrier, the efficiency by direct consumption of GABA is very low. If self-synthesis of a nerve cell can be promoted, the efficiency cannot be influenced by the blood-brain barrier.


Meanwhile, GABA can regulate autonomic nerves, alleviate tension, reduce stress, and improve sleep quality, and also has the functions of promoting secretion of a growth hormone, enhancing skeletal muscles, enhancing immunity, reducing fat, and the like. In this test, human brain nerve cells SH-SY5Y were used, and then the content of GABA secreted by the cells was detected using a GABA ELISA Kit. Whether the Sparassia crispa extract could help increase the secretion of GABA of the brain nerve cells or not was evaluated.


Material and Device Description:

Cell line: Human neuroblastoma cells (SH-SY5Y), taken from the American Type Culture Collection (ATCC), with a deposit number of Cat. CRL-2266, hereinafter referred to as nerve cells.


Cell medium: A minimum essential medium (Dulbecco's modified Eagle medium (hereinafter referred to DMEM)) (Gibco, with a product number of 12100-046) supplemented with 10% of fetal bovine serum (FBS; Thermo, with a product number of 10437-028), and 1% of penicillin-streptomycin (Thermo, Cat. 15240062).


A ELISA Kit for GammaAminobutyric Acid (gABA) (CEA900Ge) contains GABA.


Solvent: 1×DPBS (Gibco, Cat. 14200-075), a cell lysis buffer (Thermo, Cat. FNN0011).


Test Flow:

Firstly, the nerve cells were implanted into a 24-well cell culture plate at a density of 1×104 nerve cells, each well containing 0.5 ml of cell medium, and cultured in a carbon dioxide incubator at 37° C. for 24 h.


The nerve cells were divided into an experimental group and a blank group. The cell medium in each group was removed and replaced with a 500 μl/well test medium, then the test medium was placed at 37° C. and further cultured for 24 h.


The test medium in the experimental group was a cell medium containing 0.0625% of Sparassia crispa extract obtained in Example 1.


The test medium in the blank group was a pure cell medium.


Supernatant in each group was removed, and then the culture plate was washed twice with 1×DPBS and the cell lysis buffer was added to lyse the cells. Centrifugation was performed at 4° C. at 13,000 rpm for 5 min, and the supernatant was collected and stored in a 1.5 mL microcentrifuge tube. Treatment was performed with the detection kit for gamma-aminobutyric acid to obtain the GABA content in each group. The test results are as shown in FIG. 1.


The GABA content shown in the figure is presented in relative rate, where a standard deviation was calculated using an STDEV formula of Excel software, and whether there was a statistically significant difference or not was analyzed with a single-tailed student t-test in an Excel software. In the figure, “*” represents that the p value is less than 0.05, and “**” represents that the p value is less than 0.01. The more the “*”, the more significant the statistical differences.


See FIG. 1. Values in the blank group were regarded as 100%. Compared with that of the blank group, the GABA content in the experimental group was 124.6%, and there was a statistically significant difference between the experimental group and the blank group. In other words, the Sparassia crispa extract could significantly promote the secretion of GABA by the human nerve cells. It can be seen from this that the Sparassia crispa extract can improve sleep quality in humans.


Example 3: Test of Sparassia crispa Extract on Expression of Mitochondria-Related Genes
Materials and Instruments:

Cell line: Human skin fibroblasts CCD-966Sk, taken from the American Type Culture Collection (ATCC), with a deposit number of Cat. CRL-1881, hereinafter referred to as skin fibroblasts.


Cell medium: Formulated with 90% of minimum essential medium (Eagle) in Earle's BSS supplemented with ingredients to contain 0.1 mM non-essential amino acid solution, 1.5 g/L sodium bicarbonate, 1 mM sodium pyruvate, and 10% fetal bovine serum (hereinafter referred to as FBS) (purchased from Gibco).


RNA extraction reagent kit, purchased from Genemark.


SuperScript® III reverse transcriptase, purchased from Invitrogen.


ABI StepOnePlus™ Real-Time PCR system, purchased from Thermo Fisher Scientific.


KAPA SYBR FAST qPCR Master Mix (2×) Kit, purchased from KAPA Biosystems, with a product number of KK4600.


Test Flow:

The skin fibroblasts were inoculated into 6-well culture plate containing 2 mL of cell medium per well at a density of 1×105 skin fibroblasts per well, and cultured at 37° C. for 48 h.


After the culture, the skin fibroblasts were divided into several blank groups and experimental groups for comparison of expression of different genes. A culture solution in the blank group did not contain any extracts, while a culture solution in the experimental group contained 0.0625% of Sparassia crispa extract prepared in Example 1. Each group was subjected to three replicates, and cultured at 37° C. for 24 h.


The culture solutions in the cultured blank group and experimental group were removed, and rinsing was performed with PBS.


After the rinsing, a cell membrane of a HPEK-50 cell in each group was broken open with a cell lysis buffer in the RNA extraction reagent kit to form a cell solution.


RNA in the cell solution in each group was extracted using the RNA extraction reagent kit.


2000 nanograms (ng) of the RNA extracted was taken from each group to serve as a template, and the extracted RNA was reverse-transcribed by the SuperScript® III reverse transcriptase into corresponding cDNA.


A quantitative real-time reverse transcription polymerase chain reaction was performed on the cDNA by using the ABI StepOnePlus™ Real-Time PCR system, with the KAPA SYBR FASTqPCR Master Mix (2×) Kit and a combined primer of Table 1, to observe expression levels of various target genes of the HPEK-50 cells in the blank group and the experimental group and melting curves thereof. Instrument set conditions for the quantitative real-time reverse transcription polymerase chain reaction were: reaction at 95° C. for 20 s, reaction at 95° C. for 3 s, and reaction at 60° C. for 30 s, which was repeated for 40 cycles.


Relative expression levels of target genes were determined by using a 2−ΔΔCt method. The so-called relative expression level was defined as a fold change of an RNA expression level of the target gene in the experimental group relative to that of the same gene in the blank group. In the 2−ΔΔCt method, the fold change was calculated with a cycle threshold of a TBP gene as a cycle threshold (Ct) of a reference gene for internal control according to the following formula:

Here, statistically significant differences between measurement results of the blank group and the experimental group were obtained through statistical analysis of a student t-test. (In the figure, “*” represents that its p value is less than 0.05 in comparison with that in the blank group, “**” represents that its p value is less than 0.01 in comparison with that in the blank group, and “***” represents that its p value is less than 0.001 in comparison with that in the blank group. The more the “*”, the more significant the statistical difference).


See FIG. 2 for the test results. The skin fibroblasts in the blank group were not subjected to any treatment, which means that expression levels of their gene were set as 1.0 under normal physiological metabolism conditions. An expression level of CCT5 gene in a CCT5 gene experimental group was 1.8 times that of the blank group, while an expression level of CCT7 gene in a CCT7 gene experimental group was 2 times that of the blank group. It can be seen that the expression levels of the CCT5 gene and the CCT7 gene can be significantly increased after treatment with the Sparassia crispa extract, thereby enhancing mitochondrial activity.


See FIG. 3 for the test results. The skin fibroblasts in the blank group were not subjected to any treatment, which means that expression levels of their gene were set as 1.0 under normal physiological metabolism conditions. An expression level of Pink1 gene in the Pink1 gene experimental group was 2.02 times that of the blank group, while an expression level of Parkin gene in the Parkin gene experimental group was 2.05 times that of the blank group. It can be seen that the expression levels of the Pink1 gene and the Parkin gene can be significantly increased after treatment with the Sparassia crispa extract, thereby activating an energy source of the cell, and delaying aging of the cell.


See FIG. 4 for the test results. The skin fibroblasts in the blank group were not subjected to any treatment, which means that expression levels of their gene were set as 1.0 under normal physiological metabolism conditions. An expression level of Atg1 gene in the Atg1 gene experimental group was 1.8 times that of the blank group, while an expression level of Atg8 gene in the Atg8 gene experimental group was 1.6 times that of the blank group. It can be seen that the expression levels of the Atg1 gene and the Atg8 gene can be significantly increased after treatment with the Sparassia crispa extract, thereby improving cell repairing capacity.


See FIG. 5 for the test results. The skin fibroblasts in the blank group were not subjected to any treatment, which means that expression levels of their gene were set as 1.0 under normal physiological metabolism conditions. An expression level of SIRT1 gene in the SIRT1 gene experimental group was 3.5 times that of the blank group, an expression level of FOXO gene in the FOXO gene experimental group was 2.6 times that of the blank group, an expression level of PARP1 gene in the PARP1 gene experimental group was 0.8 times that of the blank group, while an expression level of SOD3 gene in the SOD3 gene experimental group was 2.1 times that of the blank group. It can be seen that the expression levels of the SIRT1 gene, the FOXO gene and the SOD3 gene can be significantly increased after treatment with the Sparassia crispa extract, thereby extending a cell lifespan, while the expression level of the PARP1 gene is inhibited, thereby enhancing the mitochondrial activity.


It can be seen from this that the Sparassia crispa extract can significantly enhance the expression levels of the ATG1 gene, the ATG8 gene, the CCT5 gene, the CCT7 gene, the Pink1 gene, the Parkin gene, the SIRT1 gene, the FOXO gene, and the SOD3 gene, and can inhibit the expression level of the PARP1 gene.


Example 4: Human Body Test of Sparassia crispa Extract

Subject: 8 subjects. Each subject was an adult aged 20 or above.


Test items: Skin laxity, expression levels of SIRT1 gene, OXO gene, and SOD3 gene in blood, GABA content in blood, skin questionnaire survey, and sleep questionnaire survey.


Regarding the skin laxity, the facial skin of the same subject before and after consumption was detected using a skin elasticity detection probe Cutometer® MPA580 (C+K Multi Probe Adapter System, Germany) purchased from the Courage+Khazaka electronic in Germany. The test principle was based on principles of suction and stretching. Negative pressure was generated on the surface of tested skin to suck the skin into a test probe. The depth of the skin sucked into the probe was detected with an optical test system, and the laxity was analyzed and calculated with software.


Human peripheral blood mononuclear cells (PBMCs) were isolated from the blood of the subject, and the expression levels of the SIRT1 gene, the FOXO gene, and the SOD3 gene were measured.


The GABA content in the blood was detected by Dajiang Gene.


Regarding the skin questionnaire survey, self-assessment was conducted on the two items: the skin laxity and skin dryness, and an option was made from the following five options: none, mild, obvious, severe, and very severe. Then the option was converted into a score for expression, where 1 point was for none, 2 points were for mild, 3 points were for obvious, 4 points were for severe, and 5 points were for very severe. A score before taking was then subtracted from a score after taking, and then the difference was divided by the score before taking, and the quotient was converted into a percentage.


Regarding the sleep questionnaire survey, self-assessment was conducted on the two items: level of light sleep and level of dreaming, and an option was made from the following five options: none, mild, obvious, severe, and very severe. Then the option was converted into a score for expression, where 1 point was for none, 2 points were for mild, 3 points were for obvious, 4 points were for severe, and 5 points were for very severe. A score before taking was then subtracted from a score after taking, and then the difference was divided by the score before taking, and the quotient was converted into a percentage.


Test Mode:

The 8 subjects in the experimental group were allowed to consume 0.35 g of the Sparassia crispa water extract prepared in Example 1 daily for 4 consecutive weeks.


Data measured before consumption (i.e., week 0) was called the blank group, and data measured after 4 weeks of consumption (i.e., week 4) was called the experimental group.


Test Results:

As shown in the figure below, on the basis of a mean of all the subjects and the data at week 0 (considered as 100% or 1), the relative value of each group was obtained by conversion. The standard deviation was calculated by using the STDEV formula of Excel software, whether there was a statistically significant difference or not was analyzed with a single-tailed student t-test in an Excel software to obtain its p-value. Moreover, in the figure, “*” represents that its p-value is less than 0.05.


See FIG. 6. The subjects in the blank group did not consume the Sparassia crispa extract, which means that an average expression level was set as 1.0 under normal physiological metabolism conditions. The 3 of the 8 subjects were excluded due to the fact that errors in experimental data were caused by poor RNA extraction quality. Here, the 3 of the remaining 5 subjects were improved in their gene expression levels, which means that the proportion of improved individuals was 60%. An average SIRT1 gene expression level of these 5 subjects in the experimental group was increased by 32.2 times in comparison to that at week 0 (blank group) after 4 weeks of consumption of the Sparassia crispa extract (experimental group), an average FOXO gene expression level of these 5 subjects in the experimental group was increased by 92.0 times in comparison to that at week 0 (blank group) after 4 weeks of consumption of the Sparassia crispa extract (experimental group), and an average SOD3 gene expression level of these 5 subjects in the experimental group was increased by 111.3 times in comparison to that at week 0 (blank group) after 4 weeks of consumption of the Sparassia crispa extract (experimental group).


See FIG. 7. After taking the Sparassia crispa extract daily for 4 weeks, the 2 subjects were excluded due to the fact that the detection probe was blocked by severe desquamation of skin to result in errors in experimental data. Here, the skin laxity of 5 of the remaining 6 subjects was decreased, which means that the proportion of improved individuals was 83.3%. Average skin laxity of 6 subjects in the experimental group was decreased from 100% (blank group) at week 0 to 89.0% (experimental group). This means that the Sparassia crispa extract can help firm the skin.


See FIG. 8. After taking the Sparassia crispa extract daily for 4 weeks, 6 of the 8 subjects showed an increase in the GABA content in their blood, which means that the proportion of improved individuals was 62.5%. The average GABA content in blood of 8 subjects in the experimental group was increased from 0.04 pg/mL (blank group) at week 0 to 0.16 pg/mL (experimental group), which means that it was increased by four times on average.


See FIG. 9. After taking the Sparassia crispa extract daily for 4 weeks, 6 of 8 subjects self-rated that the skin laxity was improved, which means that the proportion of improved individuals was 62.5%. Continue to see FIG. 9, in a case where self-rated scores of 8 subjects in the experimental group on the severity of the skin laxity were summed and a mean thereof was obtained, the mean was compared to a total score mean in an initial state (week 0), then was divided by the total score mean in the initial state, and the quotient was converted into a percentage, it can be obtained by conversion that the severity of the skin laxity was reduced by 25.0%.


After taking the Sparassia crispa extract daily for 4 weeks, 6 of the 8 subjects self-rated that the skin dryness was improved, which means that the proportion of improved individuals was 62.5%. Continue to see FIG. 9, in a case where self-rated scores of 8 subjects in the experimental group on the severity of the skin dryness were summed and a mean thereof was obtained, the mean was compared to a total score mean in an initial state (week 0), then was divided by the total score mean in the initial state, and the quotient was converted into a percentage, it can be obtained by conversion that the severity of the skin dryness was reduced by 29.2%.


See FIG. 10. After taking the Sparassia crispa extract daily for 4 weeks, 6 of the 8 subjects self-rated that dreaming at night was reduced, which means that the proportion of improved individuals was 75.0%. Continue to see FIG. 10, in a case where self-rated scores of 8 subjects in the experimental group on the severity of the dreaming were summed and a mean thereof was obtained, the mean was compared to a total score mean in an initial state (week 0), then was divided by the total score mean in the initial state, and the quotient was converted into a percentage, it can be obtained by conversion that the severity of the dreaming at night was reduced by 31.3%.


After taking the Sparassia crispa extract daily for 4 weeks, 6 of the 8 subjects self-rated that the light sleep at night was reduced, which means that the proportion of improved individuals was 75.0%. Continue to see FIG. 10, in a case where self-rated scores of 8 subjects in the experimental group on the severity of the light sleep were summed and a mean thereof was obtained, the mean was compared to a total score mean in an initial state (week 0), then was divided by the total score mean in the initial state, and the quotient was converted into a percentage, it can be obtained by conversion that the severity of the light sleep was reduced by 36.7%.
