Abstract

The invention discloses a process for extracting sphallerocarpus gracilis polysaccharide through a complex enzyme method. The process comprises the following steps: drying and grinding sphallerocarpus gracilis, adding water, implementing microwave extraction, hydrolyzing through cellulase and hydrolyzing through papain, conducting enzyme deactivation, cooling, centrifuging and reserving a supernatant liquid, extracting through two layers of filter paper, decompressing and concentrating, precipitating through ethanol, and freeze-drying to obtain the sphallerocarpus gracilis polysaccharide, wherein polysaccharide yield is 18.92-21.35%. Through a phenol-sulfuric acid method, polysaccharide content in an extract is detected to be 88.33%+ / -0.93%, and through coomassie brilliant blue, protein content is tested to be 2.17%+ / -1.03%. Experiments show that the sphallerocarpus gracilis polysaccharide has a remarkable inhibiting effect on blood sugar and blood fat of experimental hyperglycemic rats, and is safe and free from side effect. After being ground, the freeze-dried extract is prepared into tablets, hard capsules, granules and the like; and the sphallerocarpus gracilis polysaccharide is a natural healthcare product having a function of regulating blood sugar and blood fat.

Description

technical field [0001] The invention relates to a method for extracting yellow ginseng polysaccharides, in particular to a method for extracting yellow ginseng polysaccharides by a compound enzyme method. Background technique [0002] With the acceleration of the pace of life in today's society and the increase in life pressure, the number of people suffering from hypertension, hyperglycemia, and hyperlipidemia (also known as the three highs) is increasing day by day. Nowadays, the prevention and treatment of the three highs mainly depends on western medicine, such as Captopril Tablets, Compound Jiangya Tablets, Qingnao Jiangya Tablets, etc. for the prevention and treatment of high blood pressure. Drugs for hyperlipidemia such as simvastatin, Pragut, etc. Although these medicines take effect quickly, they cause greater damage to organs such as the liver and kidneys. The pure natural plant extracts have the advantages of mild action, no toxic side effects, etc., and have gr...
