Abstract

The invention discloses a method for extracting cyperus esculentus polysaccharide. The method comprises the following steps: crushing puffed cyperus esculentus, and sieving to obtain cyperus esculentus powder for later use; adding distilled water into the cyperus esculentus powder according to a liquid-material ratio of 10-20 times, and extracting soluble total sugar under an ultrasonic conditionto obtain a cyperus esculentus soluble total sugar solution; carrying out centrifugal treatment on the cyperus esculentus soluble total sugar solution, and collecting supernatant; carrying out vacuumconcentration on the supernatant to a preset volume, adding ethanol while stirring to generate a mixed solution, standing the mixed solution, carrying out centrifugal treatment, and collecting precipitates in the mixed solution through alcohol precipitation; removing residual ethanol in the precipitate, redissolving the ethanol-removed precipitate with distilled water, and carrying out vacuum freeze drying to obtain the cyperus esculentus crude polysaccharide.

Description

technical field [0001] The present invention relates to a kind of agricultural product processing technique, especially a kind of method that can efficiently extract oleophyllum polysaccharide. Background technique [0002] Oil sedge, belongs to Angiosperm, Monocotyledon, Cyperaceae, Cyperaceae, Cyperaceae. It is native to the Nile River Basin in Africa. It is also called "underground walnut" and "tiger nut". It enjoys the "fruit of life" "Reputation. It is a high-quality, high-yielding, multi-purpose new crop that integrates oil, grain, animal husbandry and animal husbandry with high comprehensive utilization value. Yassa bean has been widely and successfully planted in tropical, subtropical and temperate regions. Yousha beans do not contain gluten protein, are not easy to cause allergies, and are high-quality raw materials for the production of formula foods and special diets. Since 1952, the Institute of Botany of the Chinese Academy of Sciences introduced and successf...
