Abstract

The invention discloses a preparation method of a hypolipidemic compound Fuzhuan tea element A and application of the compound in reducing the blood fat. Aspergillus niger is inoculated to ferment tealeaves, and the Fuzhuan tea element A is purified and prepared by virtue of technologies such as column chromatography, extraction and the like. The method comprises the following steps: (1) fermenting; (2) crushing tealeaves; (3) extracting by utilizing a methanol solvent with the volume concentration of 80 percent; (4) concentrating filtrate; (5) separating and purifying by virtue of column chromatography: selecting 7cm, 5.5cm and 3cm chromatographic columns to be filled with silica gel and sephadex gel, and separating; (6) adding acetonitrile to extract; (7) freeze drying: freezing the collected supernatant in a refrigerator, and freeze drying by utilizing a freeze drying machine. The compound Fuzhuan tea element A is high in purity and can be used for preparing a hypolipidemic drug.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a blood lipid-lowering compound and its preparation method and application. Background technique [0002] Hyperlipidemia (hyperlipidemia, HLP) is a disorder of lipid metabolism in the human body, and one or more lipid components in the plasma are abnormally increased, manifested as hypercholesterolemia, hypertriglyceridemia or both. both. Hyperlipidemia can induce atherosclerosis, cardiovascular and cerebrovascular diseases, such as hypertension, coronary heart disease, cerebrovascular disease, senile dementia, etc. Therefore, the harm of hyperlipidemia has become a worldwide concern. [0003] Teadenol A (Teadenol A) was discovered and named by Japanese scholars in Japanese fermented tea, and has significant lipid-lowering effects (WulandariRA, AmanoM, YanagitaT, TanakaT, KounoI, KawamuraDandIshimaruK. Newphenolic compounds from Camelliasinensis L. leavesfermented with Aspergillus sp...
