Description

Hypoglycemic drug and preparation method and application thereof
Technical Field
The invention relates to the technical field of blood sugar reducing products, in particular to a blood sugar reducing medicine and a preparation method and application thereof.
Background
The incidence of diabetes in countries around the world is on an increasing trend year by year. According to the data related to the world health organization, the number of diabetics in the whole world exceeds 3.82 hundred million, about 1.5 hundred million people are diabetic in China, and 3.5 hundred million people are in the early stage of the diabetic. The rehabilitation of the diabetes patient becomes one of the important contents of the medical and sanitary work in China. Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by a defect in insulin secretion or an impaired biological action, or both. The long-standing hyperglycemia causes chronic damage and dysfunction of various tissues, particularly eyes, kidneys, heart, blood vessels and nerves. More than half of the deaths due to diabetes are caused by cardiovascular and cerebrovascular diseases, and 10% of the deaths are caused by nephropathy. Patients who have had amputations due to diabetes are 10-20 times more non-diabetic. Clinical data show that about 10 years after diabetes mellitus occurs, 30-40% of patients have at least one complication, and once the complication occurs, the drug treatment is difficult to reverse, so that the early prevention of diabetes mellitus is emphasized.
Many people believe that diabetes can only be delayed by western medicine. However, according to long-term clinical observation, many diabetic patients take various chemical western medicines at the early stage of disease onset, the blood sugar can be rapidly reduced, the reduction is temporary and ignorable, the nutrition absorption of the human body is blocked, the reduction is generated under the condition that the medicines have great harm and side effects on the organism, the treatment result faces the embarrassment that the medicine dosage is gradually increased and various medicines are continuously taken for replacement until the medicine is invalid, the pancreatic island function can not be fundamentally recovered by adopting the western medicine treatment mode, the purpose of treating the diabetes is achieved by enabling the blood sugar to stably reduce, and the toxic and side effects of the medicines are accumulated in the organism for a long time along with the long-term, the body is more harmful, and the problem of causing various complications is the first.
Disclosure of Invention
The invention aims to provide a hypoglycemic drug, a preparation method and application thereof, which can effectively reduce the blood sugar of a diabetic patient, improve the hyperglycemia and the constitution of the diabetic patient, can simultaneously cooperate and enhance the drug effect of the existing hypoglycemic drug, and obviously reduce the side effect after the drug is taken.
The embodiment of the invention is realized by the following technical scheme:
a preparation method of a hypoglycemic drug comprises the following steps:

s3, inoculating the cultured primary strain culture solution with the volume fraction of 5-15% into a liquid culture medium consisting of potato glucose and ginseng glucose-reducing composition, and performing shaking culture at 20-30 ℃ and 160r/min for 5-10 days to obtain poria cocos transformed ginseng fermentation liquor; vacuum concentrating Poria converted Ginseng radix fermentation liquid under reduced pressure, and freeze drying to obtain fermented concentrate;
s4, when the tablet is prepared, the method further comprises the following steps: crushing the fermentation concentrate in the step S3 to prepare superfine powder; sterilizing the superfine micropowder, adding 20-30 parts by mass of cyclodextrin and 8-14 parts by mass of water, mixing uniformly, and tabletting to obtain tablets; or when prepared into capsules, further comprises: sterilizing the superfine powder, and encapsulating to obtain capsule.
A hypoglycemic agent is prepared by the preparation method of the hypoglycemic agent.
The hypoglycemic drug is applied to the preparation of hypoglycemic, hypolipidemic or hypotensive drugs. The prepared medicine can be oral liquid, tablets, capsules, powder, granules or solid granules and the like.
The hypoglycemic medicine is applied to preparing foods for reducing blood sugar, blood fat or blood pressure. The obtained food has good health promotion effect, and can be made into beverage, gel candy or wine, etc.

tuckahoe, poria cocos: is dried sclerotium of Wolf of Poria cocos (Schw.) Cos (belonging to family Polyporaceae). Property and taste: sweet and light taste, mild nature: it is entered into heart, lung, spleen and kidney meridians; the functional indications are as follows: induce diuresis and drain dampness, invigorate spleen and calm heart. Can be used for treating dyspepsia, abdominal distention and pain, spleen deficiency, anorexia, breast pain, and female hypogalactia. The pharmacological action is as follows: (1) Pachyman has effects of reducing fasting blood glucose of rat with diabetes induced by alloxan, and Malondialdehyde (MDA) and superoxide dismutase (SOD) in liver, and has effects of reducing blood glucose and resisting lipid peroxidation; (2) The pachymic acid in Poria can target PPARG to reduce triglyceride, free fatty acid and low density lipoprotein content in blood, and simultaneously can increase high density lipoprotein concentration in blood, and sensitize peripheral tissue to insulin; (3) The strain can be used as an excellent fermentation conversion strain, can remove impurity components and improve the content of active substances. Therefore, the ginseng hypoglycemic composition is transformed by adopting a poria cocos fungus fermentation method, and the contents of flavone, polyphenol and alkaloid which are hypoglycemic active ingredients can be increased.
