Abstract

The invention discloses helicteres angustifolia polysaccharide with glycometabolism regulation activity and a preparation method and application thereof, and relates to application of helicteres angustifolia polysaccharide in the field of glycometabolism improvement, helicteres angustifolia is used as a raw material, soaked in petroleum ether for 5 h for degreasing, filtered, soaked in 80% ethanol for 5 h for decoloration, naturally aired and ground into coarse powder. Taking a certain amount of helicteres angustifolia powder, adding distilled water, soaking, carrying out ultrasonic-assisted extraction, combining extracting solutions, concentrating, centrifuging, removing protein from filtrate, carrying out alcohol precipitation, redissolving, dialyzing and freeze-drying to obtain helicteres angustifolia polysaccharide. Animal experiment results show that the helicteres angustifolia polysaccharide prepared in the invention has good glycometabolism regulation activity, can regulate the intestinal flora level, and has good development and application prospects.

Description

technical field [0001] The invention relates to the technical field of polysaccharides, in particular to a sesame polysaccharide with sugar metabolism regulating activity, a preparation method and application thereof. Background technique [0002] Diabetes is a common and frequently-occurring disease that seriously endangers human health. In recent years, the incidence has shown a significant upward trend. Diabetic patients need to take medicine for a long time and control their diet. At present, there is no good medicine to control diabetic complications. In order to better control the occurrence of diabetes, people should pay attention to the prevention of diabetes, and develop more health food with good function of improving glucose metabolism. [0003] Studies have shown that natural plants are an important treasure house for the development of hypoglycemic health foods. The polysaccharides contained in them have various activities such as immune regulation and impr...
