[0031] 1 Purification of tea crude polysaccharides

[0032] 1.1 Purification of tea polysaccharides

[0033] Dissolve 10 g of tea crude polysaccharide solution in 100 ml of water and 0.25% trypsin solution according to the volume ratio of 1 (tea crude polysaccharide solution): 0.4 (trypsin solution) and mix evenly, place in a constant temperature water bath at 37°C and heat at constant temperature for 3 hours, then Add 28ml of 10wt% H at pH=7.0 to this mixture 2 o 2 Reaction 12h;

[0034] Then put the tea crude polysaccharide solution after enzymolysis into boiling water to extinguish the fire enzyme for 10 minutes, place it at room temperature to cool, then discard the precipitate by high-speed centrifugation, take 168ml of the supernatant and put it in a beaker, add 42ml of sevage solution, and stir under magnetic force Stir vigorously on the instrument for 20 minutes, pour into a separatory funnel and let stand to separate layers, discard the protein layer and the organi...

Abstract

The invention discloses a tea polysaccharide-chromium complex as well as preparation and application thereof. The complex is a complex formed by carrying out coordination reaction on purified tea polysaccharide and chromium under a certain condition, separating and purifying. An animal activity experiment proves that the tea polysaccharide-chromium complex has a remarkable effect of lowering blood glucose of hyperglycemia mice; the effect of lowering the blood glucose of the complex is stronger than that of the inorganic chromium and the tea polysaccharide, so that the tea polysaccharide-chromium complex can be used for preparing anti-diabetes medicines and health-care foods.

Description

technical field [0001] The invention relates to a tea polysaccharide-chromium complex and its preparation and application, belonging to the field of medicine. Background technique [0002] Diabetes is a disease that seriously threatens human life and health. The whole world is committed to the research and development of new diabetes drugs. It has always been the goal of drug developers to find effective, safe, and less adverse reactions. The active ingredient in blood sugar is an important pathway. Polysaccharides have immune regulation, anti-tumor, hypoglycemic, anti-oxidation and other effects. Tea is a traditional Chinese medicine for both medicine and food, which has good functions of lowering blood sugar and blood fat. Tea leaves are widely distributed all over the world. They can be used as drinks, contain various beneficial ingredients, and have health care effects. Moreover, my country's tea leaves are rich in resources and have a long history of medicinal use. I...
