Panax ginseng belongs to the genus Panax of the Araliaceae family. It has been widely used in China, Korea and Japan for more than 2000 years. Its main purpose is to prevent diseases and prolong life expectancy. According to the records in the Shennong's Classic of Materia Medica, panax ginseng has the therapeutic effects of nourishing the five viscera, calming the nerves, settling the mind, stopping palpitation due to fright, eliminating evil, improving the eyesight and intelligence, conducive to controlling body weight and prolonging life expectancy. Modern medical studies have shown that panax ginseng's main functions and effects include regulating the central nervous system, exerting anti-cancer and anti-tumor effects, regulating immune functions, exerting anti-diabetic effects, enhancing liver function, improving cardiovascular and cerebrovascular disorders, exerting anti-arteriosclerosis effects, regulating blood pressure, improving climacteric disorders, exerting anti-osteoporosis effects, and exerting anti-fatigue, anti-oxidation as well as anti-aging effects, etc.
As the main effective components of panax ginseng, ginsenoside Rg3 and ginsenoside Rg5 have good safety profiles and have been developed as the anti-tumor oral preparations for clinical application and in-depth studies have been conducted for their dosage forms of injection.
However, the present inventors have found out that, in the prior art, the pharmacological effects of panax ginseng are either investigated by testing one or several extracted and purified ginsenosides, in which the amounts of ginsenoside Rg3 and ginsenoside Rg5 are often relatively close, or by testing the mixtures or extracts of a large number of different kinds of Chinese medicinal materials (including panax ginseng) are studied, in which the contents of ginsenoside Rg3 and ginsenoside Rg5 are usually not determined. Based on the long-term research experience in traditional Chinese medicine and modern medicine, the inventors have developed a method for preparing a composition of ginsenoside Rg3 and ginsenoside Rg5, which is not only simple, requiring mild process conditions, but also has multiple formulas for wide applications.

Drugs and water were administered once daily for 30 consecutive days.
2.2 Experiments and Results
2.2.1 ConA-Induced Mouse Splenic Lymphocyte Transformation Test
At 1 h after the last dose, the spleens of animals of each group were aseptically excised to prepare splenocyte suspension. After diluting the splenocyte suspension to a concentration of 3×106 cells/mL, the splenocyte suspension was divided into 2 aliquots. Each of the aliquot was transferred into two 24-well culture plates, respectively at a volume of 1 mL/well, and then 75 μL ConA solution (a) was added to a well, and the other well was used as control (b), which were cultured at 37° C. for 72 h. Thiazolyl blue (MTT) was added 4 h before the end of the culture. After incubation, acidic isopropanol was added, and the absorbance (ABS) of each solution was measured at 570 nm after mixing well. The proliferativity was calculated using the formula (proliferativity=ABSa-ABSb). Each dose group of the test sample was compared with the negative control group. The experimental results are shown in Table 1.
2.2.2 Determination of NK Cell Viability
At 1 h after the last dose, the spleens of animals of each group were aseptically excised to prepare splenocyte suspension. After the red blood cells were lysed with sterile water for injection, the cell suspension was diluted with 1% glacial acetic acid. Then, after adjusting the concentration of splenocyte suspension to 2×107 cells/mL, the splenocyte suspension was added to a 96-well plate for culturing. For each animal, the wells were divided into reaction wells (splenocyte suspension and YAC-1 cell suspension 100 μL each; effector-to-target ratio was 50:1); natural release wells (YAC-1 cell suspension and culture medium 100 μL each) and maximum release wells (YAC-1 cell suspension and 1% NP40 100 μL each). A triplicate set of tubes was prepared for each of the above items. The 96-well plate was incubated at 37° C. in a 5% CO2 incubator for 4 h. then, after addition of LDH matrix solution and 1 moL/LHC1, the solutions in each parallel well were combined, and the absorbance (ABS) was measured at 490 nm. Then, the NK cell viability was calculated. NK cell viability (%)=(ABSreaction well−ABSnatural release well)/(ABSmaximum release well−ABSnatural release well). The experimental results are shown in Table 8.
3. Test Results
Following the stimulation of T lymphocytes by ConA, the blast cells will show proliferative responses. The mitochondrial hydrolase in the viable cells, especially the proliferating cells, decomposes MTT into blue-purple crystals. If the optical density value is increased, it indicates that the cell proliferation ability is enhanced. As shown in Table 1, the optical density differences of the high-, medium- and low-dose groups of the ginsenoside composition were higher than those of the negative control group, indicating that this sample can promote the proliferation of splenocytes.
After the cells are killed by the NK cells, the LDH in the cytoplasm of viable cells will be released to the outside of the cells, and LDH can dehydrogenate lithium lactate, so that NAD is reduced to NADH, which in turn is reduced to iodonitro-tetrazolium chloride (INT) through hydrogen transmitter phenazine methosulfate (PMS). After receiving H+, the INT is reduced to a purple formazan compound and the optical density value is determined using a microplate reader. As shown in Table 1, the NK cell viability of the high-, medium- and low-dose groups of the ginsenoside composition was significantly higher than that of the negative control group, indicating that the sample can increase the viability of the NK cells.
The above experimental results showed that all the different doses of the composition of ginsenoside Rg3 and ginsenoside Rg5 could promote the proliferation of splenocytes, increase the viability of the NK cells, and could significantly improve the immune function.

The composition of ginsenoside Rg3 and ginsenoside Rg5 is produced by Dalian Fusheng Natural Drugs Development Co., Ltd. The contents of Rg3 and Rg5 were determined by HPLC, respectively.
The low, medium and high doses of the investigational product were 2 times, 4 times and 8 times the clinical equivalent dose for adults (calculated according to the body weight of 60 kg of adults), respectively. The suspension at the required concentration was prepared with double distilled water. The prepared drug solution was stored in a refrigerator at 4° C. and protected from light until use.
The positive control drug is cyclophosphamide (lot No.: 20130105, Jiangsu Hengrui Medicine Co., Ltd.). For the clinical equivalent dose for the adults (calculated according to the body weight of 60 kg of adults), the required suspension was prepared with double distilled water and stored in a refrigerator at 4° C. and protected from light until use.
2. Experimental Method
2.1 Grouping and Administration
Mice inoculated with sarcoma 180 (S180) ascites tumor cells which were well grown for 7 days were taken and the ascities fluid was aseptically collected, then diluted with sterile normal saline to adjust the cell number to 2×106/0.2 mL and stored in ice water until use.
A total of 300 healthy Kunming mice (half male and half female) aged 6-8 weeks and weighing 18-22 g were preliminarily housed for 1 week under the experimental conditions. After that, 10 of the animals were randomly selected as the blank control group, and the remaining 290 mice were subcutaneously inoculated with 0.2 mL of S180 tumor cell suspension in the axilla of the left hind limb of each mouse. Twenty-four hours following the inoculation, the mice were weighed and randomly divided into 29 groups, i.e., the tumor-bearing control group, positive control group and ginsenoside composition experimental group. And the animals in the latter group were further divided into the high dose groups, medium dose groups and low dose groups, respectively. Starting from the grouping day, animals in the low dose group (36 mg/kg), medium dose group (72 mg/kg) and high dose group (144 mg/kg) of the ginsenosides composition and the positive control group were administered with cyclophosphamide 45 mg/kg via oral gavage Animals in the normal control group and the model group were given equivalent amount of normal saline via oral gavage once daily.
After modeling and medication, the food intake, water intake, changes in coat color, activity, response to stimulation, presence of diarrhea, emaciation and death of mice in each group were observed and recorded at any time. Drugs were discontinued on the 21st day after oral gavage administration. On the next day, the mice were sacrificed by cervical dislocation and weighed. The subcutaneous tumor tissues of the left hind limb were completely stripped and weighed using an electronic balance after removing all the non-tumor tissues, such as blood stain and fat. The tumor inhibition rate was calculated according to the following formula:
Tumor inhibition rate=(average tumor weight of control group-average tumor weight of treatment group)/average tumor weight of control group×100%
2.2 The data were expressed as mean±standard deviation (±s). The inter-group comparison of the measurement data was subjected to one-way analysis of variance using SPASS 13.0 statistical software. p<0.05 indicates statistically significant differences.
3. Experimental Results
3.1 Observation of General Conditions of Animals after Administration
After administration, the mice in all the groups were alive; the mice in the blank control group had normal food and water intake, flexible movement, quick reaction, shiny hair coat, and had no diarrhea or emaciation. In comparison, the general condition of the mice in each dose group of ginsenoside composition was inferior to those of the blank control group. Mice in the positive control group had poor food and water intake, slow movement, slow reaction, shedding and dull hair coat color, diarrhea and emaciation. The general conditions of the mice in the tumor-bearing control group were the worst, with little food intake and activity, slow reaction, haggard hair coat, and obvious emaciation.
3.2 The weight of transplanted tumors and tumor inhibition rates of the mice in each group are shown in Table 10.
The experimental results showed that the weight of transplanted tumors in mice of the treatment group was significantly lower than those in the control group, indicating that the ginsenoside compositions A, B, C had an anti-tumor effect on transplanted S180 sarcoma in mice, and the tumor inhibition rates of ginsenoside compositions A, D, G were greater than 50%, which sufficiently indicated that the ginsenoside compositions had prominent tumor inhibiting effect.

Six replicate wells were set up for each drug.
3. Experimental Results
The cytotoxic effects of the chemotherapeutic drugs were detected 24 h later. The results showed that the OD value (absorbance) of the cells in the experimental group was significantly lower than that in the control group, indicating that the viability of the cells in the experimental group was significantly lower than that in the control group, and the cytotoxic effect of the chemotherapeutic drugs on the cells in the experimental group was significantly more potent than that in the control group, indicating that the ginsenoside composition experimental group had the effect of reversing drug resistance. The results are shown in Table 12.
Exemplary Test 4: Experiment of Ginsenoside Composition in Relieving Side Effects (Vomiting) of Radiotherapy and Chemotherapy
1. Experimental Materials
1.1 Drugs and Reagents:
The ginsenoside composition is white to brownish yellow powder manufactured by Dalian Fusheng Natural Drugs Development Co., Ltd. Its content was determined by high performance liquid chromatography (HPLC) with two kinds of detectors and UV detector and using the reference standard of National Institute for the Control of Pharmaceutical and Biological Products as the external standard. See Table 13 for details.
Positive control drug: metoclopramide Injection (Tianjin Renmin Pharmaceutical Factory, strength: 1 mL/10 mg, lot No.: 14060129);
Kaolin (Shanghai Fengxian Fengcheng Reagent Factory, lot No.: 1140528);
Preparation of kaolin for rats: 1 g of acacia gum was weighed and added with 100 mL of distilled water, then it was placed on a magnetic stirrer and stirred until completely dissolved; then an appropriate amount of kaolin which has been sieved through a 80 mesh sieve was taken and slowly added into the above solution while stirring, allowing it to form into a dough-like shape. Then, it was squeezed into a 5 mL syringe until the syringe was completely filled; then the plunger rod was pushed to prepare small rods with very smooth edges with the shape resembling that of normal foods; then the rods were placed into a dryer filled with blue silica gel particles and allowed to dry for later use.
1.2 Experimental Animals:
Male Wistar rats, weighing 200-220 g, were purchased from the Experimental Animal Center of Dalian Medical University, with quality certificate No.: SCXK (13) 2013-0002.
2. Experimental Method
Rats are rodents with no vomiting reactions. The pica behavior of rats after vestibular stimulation is equivalent to the reaction of vomiting of other animals, which can be regarded as a typical symptom of motion sickness in rats.
2-1. Breeding of Rats for Acclimation
Before the initiation of the experiment, the rats were bred for acclimation, that is, the quantified routine feeds and kaolin feed were given to the rats simultaneously. Two kinds of feeds were taken out and weighed at regular time points every day to observe bite marks on the feed surface until the rats almost no longer gnawed the kaolin, and then the formal experiment was started.
2-2 Pica Test
Wistar rats were randomly divided into 29 groups (with 6 rats in each group), namely the model control group, the positive drug control group, the ginsenoside composition experimental group and the last group was further divided into three groups, i.e., the low-, medium- and high-dose groups.
The rats in the model control group were given saline at 10 mL/kg via oral gavage; those in the positive control group were intraperitoneally injected with metoclopramide at 2 mg/kg; and those in the low-, medium- and high-dose groups of ginsenoside composition were administered with ginsenoside compositions A-I at 15 mg/kg, 30 mg/kg and 60 mg/kg, respectively.
At 30 min post-dose, rotatory stimulation was applied using the rotatory stimulation device modified from a centrifuge to induce motion sickness, with the rotatory speed of 100 rotations/min and rotate for 1 h.
The rats of each group were observed for the kaolin ingestion pica behavior and the consumption of routine diet and kaolin was recorded within 24 h after the rotatory stimulation was stopped.
3. Test Results
All the data were expressed as mean±standard deviation (X±S), and the PPMS medical statistical software was used for the analysis of variance and the significance test by comparing the P values. The statistical results of the consumption of routine diet and kaolin are shown in Table 14.
The experimental results showed that:
The main side effect of radiotherapy and chemotherapy was vomiting, which was reflected in the pica behavior of kaolin ingestion of the rats. In each of the ginsenoside composition dose group, the pica behavior of kaolin ingestion of the rats was significantly inhibited, and the amount of kaolin intake was significantly decreased compared with the blank control group (P<0.05, P<0.01). In each dose group of the ginsenoside composition, the treatment could significantly increase the food intake of the rats. The results of the above experiments showed that ginsenoside composition has a significant effect in alleviating emesis caused by radiotherapy and chemotherapy. Hence, the composition has good prospects for clinical application.

A total of 280 selected male mice were firstly bred for 8 weeks, bred for acclimation for 1 week and then provided with exercise training for 1 week.
They were randomly divided into 28 groups according to body weight, including the control group and the ginsenoside composition experimental groups, and animals in the latter group were further divided into high dose group, medium dose group and low dose group, respectively.
Animals in the control group were given normal saline; those in the low dose ginsenoside composition group were given low dose of ginsenoside composition (3.2 mg/kg); those in the medium dose group were given medium dose of ginsenoside composition (6.4 mg/kg); and those in the high dose group were given high dose of ginsenoside composition (12.8 mg/kg). The drug was administered once daily for 30 consecutive days.
2.3 Experiments and Results
Exhaustive Swimming Test
The dimension of the swimming pool is 185 cm×73 cm×58 cm, and it was 30 cm deep when the animals were swimming, and the water temperature was 27±1° C. Nude mice were put into the swimming pool, and the time interval from going into the water to swim to the time of exhaustion was recorded. The judgment standard for exhaustion is that the mice demonstrate obvious movement disorder, with the head sinking into the water and failing to rise above the water surface for 8 s.
Determination of SOD Activity
The activity of SOD in the blood is an important indicator of the body's anti-fatigue ability. It can be used to evaluate the fatigue index.
The data in this table showed that the exhaustive swimming duration of the mice in the ginsenoside composition groups was significantly longer than that in the control group, and the SOD activity was significantly higher than that in the exhaustive swimming group with a significant difference, indicating that the ginsenoside composition has a prominent anti-fatigue effect.
