The present disclosure relates to the field of health care products, specifically to a powder formulation, a method for preparing the same and use thereof, and more specifically to a powder formulation mainly made from natural Chinese herbal medicine and having hypoglycemic and hypolipidemic functions and the method for preparing the same.
Hyperglycemia and hyperlipidemia are “rich people's diseases” derived from modern life, and they exist either alone or linked to each other. Hyperlipidemia and hyperglycemia are sources of many diseases. Hyperglycemia causes lesions in various tissues and organs of the body, resulting in the occurrence of acute and chronic complications, for example, pancreatic failure, dehydration, electrolyte imbalance, nutritional deficiency, decreased resistance, impaired renal function, neuropathy, fundus diseases, diabetes and so on. Hyperlipidemia is a risk factor of stroke, coronary heart disease, myocardial infarction, and sudden death. In addition, hyperlipidemia is also an important risk factor for promoting abnormal glucose tolerance and diabetes. Hyperlipidemia also leads to fatty liver, liver cirrhosis, cholelithiasis, pancreatitis, retinal hemorrhage, blindness, peripheral vascular disease, claudication and hyperuricemia.
People's living standard has increased significantly in recent years, and consumption concept and health concept of people have changed a lot. In order to avoid the adverse effects of being unhealthy, people pay more and more attention to the use of nutraceuticals. Currently, most of the health care foods for improving hypertension, hyperglycemia and hyperlipidemia are in the form of oral liquid. Oral liquid has disadvantages of inconvenience of carrying, poor stability and short storage time. Large doses of adjuvants such as starch and hydroxymethyl cellulose are often added to the tablet when the tablets are made, which causes a long disintegration time. At the same time, it is inconvenient for people who have dysphagia, such as old people and children.

The powder formulation sample prepared in Example 3 was used for the functional experiments.
In the experiment, there were three dosing groups, one model group, one positive control group (metformin hydrochloride tablets), one blank group and one negative control group. The methods for preparing the samples were shown hereinafter.
Method for preparing the solution of the test sample (500 mg/kg): 2.3011 g of the test sample was precisely weighed and 46 mL of distilled water was added to prepare a solution of 0.05 g/mL, i.e., high-dose group of the test sample (500 mg/kg, 1 mL/100 g), which was equal to 30 times the recommended amount for human.
Method for preparing the solution of the test sample (170 mg/kg): 0.6970 g of the test sample was precisely weighed and 41 mL of distilled water was added to prepare a solution of 0.017 g/mL, i.e., medium-dose group of the test sample (170 mg/kg, 1 mL/100 g), which was equal to 10 times the recommended amount for human.
Method for preparing the solution of the test sample (85 mg/kg): 0.3396 g of the test sample was precisely weighed and 40 mL of distilled water was added to prepare a solution of 0.0085 g/mL, i.e., low-dose group of the test sample (85 mg/kg, 1 mL/100 g), which was equal to 5 times the recommended amount for human.
Method for preparing the negative control group (normal animal group): test sample solution (500 mg/kg): 2.3011 g of the test sample was precisely weighed and 46 mL of distilled water was added to prepare a solution of 0.05 g/mL, i.e., negative control group (500 mg/kg, 1 mL/100 g), which was equal to 30 times the recommended amount for human.
Method for preparing the positive control sample: the metformin hydrochloride tablet was milled into fine powders by a mortar, 0.1470 g powder was precisely weighed and transferred to a 10 mL-centrifugal tube. 5 mL of distilled water was added by a pipette to prepare a solution with a concentration of 0.023 g/mL, i.e., metformin positive control group for mouse (230 mg/kg, 0.1 ml/10 g), which was equal to 13.5 times the recommended amount for human.
The mice were weighed after 1-day adaptive feed, and the mice were weighed once a week and recorded.
The administration of test sample to the rats lasted for 45 days, and the administration to mice lasted for 55 days.
After 3-day of adaptive housing with normal feeding, 15 mice were randomly chosen and subjected to fasting for 3 to 5 hours. The fasting blood glucose value was measured as the basal blood glucose value of this batch of animals. Thereafter, the mice were subjected to fasting for 24 hours (with free access to water). Except for the blank group and the negative control group, 96 mg/kg of alloxan (fresh prepared) were injected via caudal vein to establish the model, at an administration amount of 0.1 mL/10 g. 4 days later, the animals were fasted for 3 to 5 hours and the blood glucose was tested. Animals with blood glucose of 10 to 25 mmol/L were considered as hyperglycemia model animals. The fasting blood glucose value of mice was tested every two week. After the experiments, animals in each group were fasted for 3 to 4 hours, and the fasting blood glucose, glucose tolerance, blood glucose decreasing rate and the area under the blood glucose curve were tested.
The mice were subjected to euthanasia and dissection. Hearts, livers, spleens, lungs, kidneys and pancreases of the mice were weighed, imaged and recorded, respectively. The organ coefficients were calculated. In addition, pancreases from each group were respectively immersed into formalin-containing bottles, and the sections were sent for pathological examination.
It can be concluded from the Table 1 that after alloxan modeling of the animals, body weights of the animals obviously decreased and showed representative characteristics of diabetes, i.e., three aspects were high and one aspect was low (eating a lot, drinking a lot, urinating a lot, while low weight). The test sample alleviated the decrease of the mouse weight, and increased body's resistance to adverse reaction. Especially in the later period of the experiments, the medium- and high-dose group showed significant differences. In addition, in the later period (the 55th day of administration), the body weight of the negative control group mice was controlled, wherein comparing with the weight of the mice in the blank group, there was no statistically significant difference, but the weight was obviously decreased.
After administration of the test sample, the hearts, livers, spleens, lungs, kidneys and pancreases of the mice in each group were weighed respectively, and organ coefficients of each group were compared. The results were shown in Table 2.
It can be concluded from Table 2 that the test sample in each group did not have obvious effects on organ coefficients of the mice, indicating that the test sample was relative safe.
As shown in Table 3, comparison of the blank group and the model group indicated that the modeling was successful. There was no significant change in the blood glucose level between the negative control group and the blank group, indicating that the drug has no effect on blood glucose of normal animals. There were significant differences between the positive control group and the model group, indicating that metformin significantly improved symptom of the hyperglycemia. In the first 30 days, there was no significant difference between the high-, medium-, and low-dose group of the test sample and the model group, indicating that the test sample had no significant effect on lowering blood glucose level. However, when extending to the 45th day, the high-dose group showed a significant effect on lowering blood glucose level (P<0.05). Continuously administrating to the 55th day, the fasting blood glucose level was tested again, and the results showed that the high-dose group has a significant effect on lowering blood glucose level and the effect was better than that of the positive control group (P <0.05).
It can be concluded from the Table 4 that the high-dose group obviously improved the area under the blood glucose curve of the alloxan-induced mice (P<0.01), and the effect of which was even better than that of the positive drug metformin.
As shown in Table 5, on the 55th day, the high-dose group significantly lowered the blood glucose level of the diabetic mice, and the administration effect in long term was better than that of the metformin.
From the researches above we found that the powder formulation prepared in the Example 3 has no effect on blood glucose of normal mice, but can control the body weight of the mice and improve quality of their lives (mainly performed in aspects such as hair color, liveness and so on). In addition, high-dose administration in the long term improved the blood glucose level of the mice. Although it did not reach drug efficacy, it met the evaluation standard of hypoglycemic of health care food.
The powder formulations obtained in Example 1 and Example 2 have a similar effect as that of Example 3.
In the experiment, there were three dosing groups of the test sample, one model group, one positive control group (metformin hydrochloride tablets) and one blank group. The method for preparing the three test sample groups were shown hereinafter.
Method for preparing the solution of the test sample (500 mg/kg): 2.3011 g of the test sample was precisely weighed and 46 mL of distilled water was added to prepare a solution of 0.05 g/mL, i.e., high-dose group of the test sample (500 mg/kg, 1 mL/100 g), which was equal to 30 times the recommended amount for human.
Method for preparing the solution of the test sample (170 mg/kg): 0.6970 g of the test sample was precisely weighed and 41 mL of distilled water was added to prepare a solution of 0.017 g/mL, i.e., medium-dose group of the test sample (170 mg/kg, 1 mL/100 g), which was equal to 10 times the recommended amount for human.
Method for preparing the solution of the test sample (85 mg/kg): 0.3396 g of the test sample was precisely weighed and 40 mL of distilled water was added to prepare a solution of 0.0085 g/mL, i.e., low-dose group of the test sample (85 mg/kg, 1 mL/100 g), which was equal to 5 times the recommended amount for human.
Method for preparing the positive control sample: the metformin hydrochloride tablet was milled into fine powders by a mortar, 0.9329 g powder was precisely weighed and transferred to a 100 mL-beaker. 43 mL of distilled water was added by using a 100 mL-graduated cylinder, preparing solution with a concentration of 0.017 g/mL, i.e., metformin positive control group for rat (170 mg/kg, 1 ml/100 g), which was equal to 10 times the recommended amount for human.
The rats were weighed after 1-day adaptive feed, and the rats were weighed once a week and recorded.
After 5-day of adaptive housing with normal feeding, the rats were fasted for 3 to 4 hours and blood samples were taken from the tails. The fasting blood glucose value, which was the blood glucose value before administration of glucose (0 hour), was tested. After administration of 2.5 g/kgBW glucose, the blood glucose level was tested at the 0.5 hour and the 2nd hour as the basal value of that batch of animals. The rats were divided into 6 groups according to the blood glucose value at 0 hour and the 0.5 hour, including one blank group, one positive control group, one model group and 3 dosing groups of the test sample. There were 20 rats in the high-dose group, and 18 rats in the other groups. The blank group was not treated. The positive control group was administered with metformin solution by intragastric gavage. The 3 dosing groups of the test sample were administered with test sample solutions of different concentrations by intragastric gavage. The model group was administered with the solvent of the same volume. The administration lasted for 45 days. Normal feeds were provided to all groups. One week later, high calorie feeds were provided to the model group, positive control group and three dosing groups of the test sample. 30 days after the feeding, the rats were fasted for 24 hours. The model group and the three dosing groups of the test sample were respectively peritoneal injected with alloxan of 200 mg/kgBW (the injection amount was 1 mg/100 g weight) on the base of high calorie feed. The model group and 3 dosing groups of the test sample were continuously fed on high calorie feeds for 3 days. When the experiment ended, animals in each group were fasted for 3 to 4 hours, and the fasting blood glucose, glucose tolerance and area under the blood glucose curve were measured.
After the experiment, the rats in each group were fasted for 3 to 4 hours and peritoneal injected with pentobarbital sodium solution (1 mL/100 g) for anesthesia. 8 mL of blood was taken from the femoral artery and centrifuged at 4500 r for 6 minutes at 4° C. The serum was taken and the cholesterol level was tested by a cholesterol kit, and the triglyceride level was tested by a triglyceride kit.
The rats were subjected to euthanasia and dissection. Hearts, livers, spleens, lungs, kidneys and parts of the pancreases of the rats were weighed, imaged and recorded, respectively. The organ coefficients were calculated. In addition, pancreases from each group were respectively immersed into formalin-containing bottles.
The Table 6 showed that body weight of the diabetic rats rose obviously in the medium period of the experiment, which was much more than the weight of the normal rats. However, in the later period, there was an obvious reduction, which was in line with the typical characteristics of type II diabetes.
Comment: the low dose was equal to 5 times of the human recommended amount, the medium dose was equal to 10 times the recommended amount for human and the high dose was equal to 30 times the recommended amount for human.
As shown in Table 8, the blank group showed significant difference (P<0.001) compared with the model group, indicating that the modeling was successful. The fasting blood glucose results demonstrated: there were significant differences between the positive control group and the model group, indicating that metformin significantly improved symptom of the hyperglycemia; after 45-day administration of the test sample, there were significant differences between the medium-dose and high-dose groups and the model group, indicating that the test sample has relatively obvious effect on lowering the blood glucose level (P<0.05, P<0.01), and presented a certain dose-dependent effect.
It can be concluded from Table 9 that in the glucose tolerance test, area under the blood glucose curve at the 2nd hour of the positive drug metformin showed significant differences, while the test sample groups did not show statistically significant difference. However, among the test sample groups, there was a certain dose-dependent effect.
The results were shown in Table 10.
It can be concluded from Table 10 that after long-time high-fat high-carbohydrate feeding, the rats presented symptoms of hyperglycemia and hyperlipidemia. When comparing with the blank group, the levels of triglyceride and cholesterol in serum of the model group increased significantly (P<0.001). All the groups administered with test sample have relatively good effect on lowering blood lipid level; especially for triglycerides, all the groups showed statistically significant differences, and the medium-dose group has the best drug efficacy.
Under the conditions of the present experiments, long-term administration of the powder formulation prepared in Example 3 decreased the blood glucose level and blood lipid level in insulin resistance rats, and these effects were similar to that of the positive drug metformin hydrochloride, thus indicating that the powder formulation has relatively good hypoglycemic and hypolipidemic functions, and it was adapt to be used for health care food.
The powder formulations obtained in Example 1 and Example 2 have similar effects as that of Example 3.
