Background

For the control of three highs, the most effective means is medicine, and the hyperlipemia patients can take the medicine for reducing blood fat, such as simvastatin, atorvastatin, xuezhikang, etc. The hypertension patients can take captopril, irbesartan, amlodipine and other medicaments. Patients with hyperglycemia can take glipizide and metformin, and can also inject insulin. And then adding diet control, for example, the total amount of salt is not more than 6 g per day, the food with high fat content is required to be eaten less, the sweet food is required to be eaten less, the diabetic patients are required to limit the intake of the staple food, and the staple food is not more than 250g per day.

The herbal ferment is a fermented beverage which is prepared by taking medicinal and edible traditional Chinese medicinal materials as raw materials and fermenting the raw materials by microorganisms and has high-content active ingredients such as organic acid, polyphenol, amino acid, vitamin, polysaccharide, polyphenol and microorganism metabolites. Because the components have the effects of resisting oxidation, supplementing nutrient substances of human bodies and improving the health of the human bodies, the products containing the ferment are quite popular with consumers in the market at present.

Long-term traditional Chinese medicine experiments and researches in China show that many traditional Chinese medicines can achieve the effect of reducing high blood pressure, high blood fat and atherosclerosis, namely, the traditional Chinese medicines comprise cassia tora, hawthorn, dried orange peel, ginkgo leaf, medlar, chrysanthemum and the like; the Chinese medicinal materials for lowering blood pressure include radix Stephaniae Tetrandrae, radix Puerariae, fructus crataegi, flos Chrysanthemi Indici, herba Catharanthi rosei, fructus forsythiae, prunellae Spica, etc.; the Chinese medicinal materials for reducing blood sugar comprise Ginseng radix, radix astragali, poria, atractylodis rhizoma, rhizoma Atractylodis, rhizoma Dioscoreae, rhizoma Polygonati, rehmanniae radix, radix Ophiopogonis, etc. Because part of the traditional Chinese medicinal materials have high toxicity and bitter taste, the traditional Chinese medicinal materials have poor utilization rate after entering human bodies, and the traditional Chinese medicines are not convenient to drink after being decocted. In addition, most of the enzyme beverage products on the market are prepared by natural fermentation, so that the effective ingredients cannot be fully dissolved out, raw material waste is easily caused, and other microbial contamination is easily caused. In addition, the natural fermentation period of the ferment is very long, generally 2-4 months, and cannot meet the large demand of the market.

			Enzyme control group	129.3±7.9	108.6±7.5
Enzyme preparation set	146.5±8.2	126.5±7.7

As can be seen from Table 2, the ferment prepared by the invention has a certain effect of preventing rat hypertension induced by high-fat high-sugar feed.

2. Lipid and blood sugar lowering test

Selecting Kunming mice with the weight of (20 +/-2 g), after adaptively feeding the Kunming mice for one week, randomly extracting 10 mice of each half of males and females to serve as a normal control group, fasting the rest mice overnight, carrying out intraperitoneal injection on Streptozotocin (STZ) with a single high dose (60 mg/kg) for modeling, injecting citric acid-sodium citrate buffer solution with the same volume into the normal control group, after one week, fasting the mice for 6 hours, and carrying out tail vein micro-blood sampling to measure the blood sugar value of an animal model, wherein the mice with the weight of more than or equal to 16mmol/L are successful in modeling. The 20 successfully molded diabetic mice were randomly divided into two groups, each group was half male and female, and each group was fed with normal feed. The experimental group was administered by gavage (enzyme of example 1) daily in an amount of 1mL/100g of body weight, and the normal control group and the model group were administered with the same amount of physiological saline. After 8 weeks of continuous administration, the mice were fasted for 6 hours, blood was taken from the tail vein, centrifuged at 3500r/min for 10min, serum was separated, and the serum blood glucose, triglyceride (TG), and cholesterol (TC) concentrations were measured using each kit, as shown in Table 3.

TABLE 3 influence of the enzyme of the present invention on blood glucose and blood lipid in mice

Group of	Blood sugar (mmol/L)	TC(mmol/L)	TG(mmol/L)
				Normal control group	5.33±0.36	2.62±0.34	0.87±0.10
Model set	29.74±1.35	4.02±0.51	1.98±0.73
				Experimental group	16.25±2.39	3.17±0.32	1.38±0.33

As can be seen from Table 3, the enzyme prepared by the invention has a certain down-regulation effect on blood sugar and blood fat of drug-induced diabetic mice.

In conclusion, the ferment prepared by the invention has certain prevention and down-regulation effects on hypertension, hyperlipidemia and hyperglycemia, and meanwhile, the traditional Chinese medicine active extract with the effect of reducing hypertension, hyperlipidemia and hyperglycemia is compounded with the fruit and vegetable ferment, so that the traditional Chinese medicine is more easily accepted by the public, and through the decomposition effect of microorganisms, nutrient substances in various raw materials are more easily absorbed and utilized by human bodies, and the immunity can be improved, the hypertension, the hyperlipidemia and the hyperglycemia can be prevented, and the body can be strengthened after long-term drinking of the ferment.

Test example 2

The enzymes obtained in example 1 and comparative examples 1 and 2 of the present invention were subjected to DPPH radical scavenging test, hydroxyl radical scavenging test and ABTS radical scavenging test, respectively, and three parallel tests were performed for each group, and the results of the scavenging rates are shown in table 4.

TABLE 4 clearance of different enzymes

Group of	DPPH clearance (%)	Hydroxyl radical scavenging rate (%)	ABTS clearance (%)
				Example 1	52.3	68.7	46.8
Comparative example 1	38.9	50.5	40.3
				Comparative example 2	42.8	52.0	39.8

As can be seen from the above table, compared to the ferment of comparative examples 1 and 2, the ferment of the present invention has better effects of removing DPPH, hydroxyl radical, ABTS radical, and has better antioxidant effect. In the comparative example 1, the raw materials of the medicinal materials are directly subjected to microbial fermentation without being subjected to extraction of soluble components, so that the oxidation resistance of the raw materials is influenced to a certain extent; in comparative example 2, although the Chinese medicinal material is extracted by soluble components, the active ingredients of the Chinese medicinal material cannot be completely decomposed and converted due to the fact that only one kind of bacteria is inoculated for fermentation, and therefore the oxidation resistance is also influenced to a certain extent.
