| titleOfInvention | Preparation method and application of modified morchella polysaccharide |
| abstract | The invention discloses a preparation method of modified morchella polysaccharide, which comprises the following steps: (1) cleaning Morchella esculenta, removing impurities, sterilizing at high temperature, oven drying, pulverizing, sieving, and extracting Morchella esculenta polysaccharide by water extraction and ethanol precipitation; (2) adding the morchella polysaccharide into aqueous hydrogen peroxide, adding a disodium hydrogen phosphate-sodium dihydrogen phosphate buffer solution for reaction, concentrating after the reaction is finished, and freeze-drying to obtain the modified morchella polysaccharide. According to the invention, the morchella polysaccharide is modified by using a hydrogen peroxide oxidation method, and the inhibition rate of the modified morchella polysaccharide on alpha-amylase is obviously improved; meanwhile, the inhibition rate of sucrase, the inhibition rate of maltase and alpha-glucosidase are correspondingly improved; compared with acarbose at the same concentration, the modified morchella polysaccharide has no obvious difference between the inhibition rate of sucrase and acarbose, and the inhibition rates of other three glycosidases are correspondingly improved. |
