Evaluation of blood lipid-lowering efficacy
(1) The detection basis is as follows: ministry of health care food inspection and evaluation technical Specifications (2003 edition). The kudzu tea soup prepared in examples 1 to 3 and comparative example was used as a test sample.
(2) And (3) high-fat feed formula: 78.8% of basal feed, 1% of cholesterol, 10% of egg yolk powder, 10% of lard oil and 0.2% of bile salt.
(3) Experimental animals: SD healthy adult male rats 140, body weight 180 + -5 g. Basal feeds were fed under experimental conditions for 7 days and TC, TG and HDL-C levels were determined. And then feeding the hyperlipidemia model for 7 days by using a high-fat feed, taking tail blood, measuring the TC, TG and HDL-C levels of the serum, wherein the TC, TG and HDL-C levels of the serum are increased and have significant difference (P is less than 0.05) compared with the levels before feeding the high-fat feed, and judging that the modeling of the hyperlipidemia model is successful. Rats after successful molding were randomly divided into 1 high fat control group, 10 example groups and 3 comparative example groups, 10 per group, according to TC levels.
(4) The experimental method comprises the following steps: the dose for the rat experiment was set to 0.85ml/kg daily. 5g of the sample is dissolved in 100mL of distilled water at 50 ℃ to form tea soup, and the tea soup is orally administrated by gavage once a day, wherein the gavage volume is 0.5mL/100g of the weight of a mouse. The high-fat control group, in which the samples of the present invention were replaced with distilled water, was continuously fed for 30 days with the same daily gavage volume as the above groups, and was fasted for 16 hours after the end of feeding on day 30, and then serum TC, TG and HDL-C levels were measured, with the results shown in table 1.
(5) Data processing: variance analysis is carried out on the serum TC, TG and HDL-C levels of rats in each group, and the P is less than 0.05, which indicates that the differences are significant.
TABLE 1 analysis results of serum TC, TG and HDL-C levels of rats of each group
| Group of | TC(mmol/L) | TG(mmol/L) | HDL-C(mmol/L) |
| High fat control group | 5.579±0.573 | 1.899±0.654 | 1.996±0.223 |
| Example 1 | 4.061±0.544* | 1.120±0.330* | 2.598±0.332* |

| Comparative example | 4.625±0.428* | 1.351±0.211* | 2.101±0.126* |
Comparing the experimental data of examples 1-3 in table 1 with the control group, it can be found that the composition prepared by the invention not only has good effect of reducing the content of TC and TG in serum, but also has effect of increasing the content of HDL-C in serum, and has obvious effect of assisting in reducing blood fat.
The blood fat reducing effect is detected by adopting the following method:
(1) the compositions prepared in examples 1 to 3 and comparative example were used as samples;
(2) experimental animals: SD healthy rats, divided into 10 groups on average;
(3) the dosage was 0.85g/Kg & BW. Preparing a sample by using normal saline, orally administering once a day, continuously performing intragastric administration for 30 days, and then measuring various indexes, wherein the intragastric volume of a rat is 0.5mL/100g of the weight of the rat, the normal saline is used for replacing the sample in the invention in a control group, and the intragastric volume per day is the same as that in the above groups;
(4) and (3) high-fat feed formula: 78.8% of basal feed, 1% of cholesterol, 10% of egg yolk powder, 10% of lard oil and 0.2% of bile salt by weight;
(5) the experimental method comprises the following steps: feeding basal diet to rats under experimental environment for 10 days, fasting the rats for 16 hours, taking blood to measure the average concentration of serum Total Cholesterol (TC), Triglyceride (TG) and high density lipoprotein cholesterol (HDL-C), then separately gavaging the provided samples while feeding high fat diet, feeding physiological water with the same volume to a control group, fasting the rats for 16 hours after 30 days, and measuring the average concentration of TC after feeding;
(6) and (3) calculating: the rate of change of TC (mean concentration after feeding-mean concentration before feeding)/mean concentration before feeding x 100%, results are shown in table 1:
TABLE 2 serum Total Cholesterol Change results
| Group of | Number of examples | 0 rate of change of TC (%) (at the end of the month) | 1 month end TC Change (%) | 2-month end TC Change Rate (%) |
| Example 1 | 10 | 15.32 | 18.32 | 24.33 |
| Example 2 | 10 | 15.89 | 18.99 | 26.61 |
| Example 3 | 10 | 15.32 | 18.32 | 24.98 |
