Abstract

The invention provides a new medical application of a Chinese traditional medicine fructus ligustri lucidi and the producing method of the extract thereof, which is produced by following steps: ethanol circumfluence, extracting and concentrating from the plant fructus ligustri lucidi to get an ethanol extract, separation by crystallization with the hydrochloric acid function, NaOH treating, again acid out, washing, drying, obtaining other effective components. Pharmacological experiments prove that the medicine can be used for treating the II-type diabetes and induced complication, which has the effects such as reducing the blood sugar, triglyceride, total cholesterin, and low density lipoprotein, and increasing the high density lipoprotein and etc. Furthermore, it can avoid the weight decrease and has a long action and no side effects.

Description

technical field [0001] The invention relates to a non-synthetic hypoglycemic drug for treating endocrine-metabolic system non-insulin-dependent diabetes mellitus (NIDDM, ie type II) and preventing its complications. It is prepared from Chinese herbal medicine Ligustrum lucidum. Background technique [0002] Diabetes is a common disease that seriously endangers human health. It currently accounts for 5% of the world's population. The death rate caused by its complications ranks third, second only to cardiovascular and cerebrovascular diseases and cancer, and it is increasing year by year. Its occurrence is related to nutritional conditions, obesity, heredity, emotion and other factors, and more than 85% of them are non-insulin-dependent diabetes mellitus (type II). The basic pathological changes of diabetes are hyperglycemia caused by metabolic disorders of sugar, fat, protein, water and electrolytes due to absolute or relative insulin deficiency, often accompanied by hyperli...
