Abstract

The invention relates to the technical field of extraction of active ingredients of edible mushrooms, and particularly relates to a method for simultaneously extracting polysaccharide and polyphenol from needle mushrooms. The method comprises the steps: preparing an extraction solution, extracting an alkaline solution by assistance of ultrasonic wave, performing enzymolysis on residue, extracting polyphenol from ethyl acetate and extracting polysaccharide after ultrafiltration and desalination. According to the method, operations such as auxiliary extraction, enzymolysis and membrane filtration are organically combined, and the polysaccharide and the polyphenol are simultaneously extracted, so that the production process is simplified, the safety and reliability are achieved, the yield is high, the physiological and pharmacological activities of the polysaccharide and the polyphenol in a needle mushroom sporocarp are well reserved, and a larger economic value is achieved.

Description

technical field [0001] The invention relates to the technical field of extracting effective components of edible fungi, in particular to a method for simultaneously extracting polysaccharides and polyphenols from Flammulina velutipes. Background technique [0002] Flammulina velutipes (Flammulina velutipes) has another name called mushroom, winter mushroom, belongs to fungi door, Basidiomycetes, Agaricaceae, Tricholomaceae, Chrysanthemum genus. Flammulina velutipes is extremely nutritious, and has the laudatory titles such as Zengzhi mushroom and "Yixiu mushroom". It is a famous edible fungus in the world and has developed into the third largest edible fungus at present. Flammulina velutipes is tender and refreshing, delicious and fragrant, and rich in nutrition. It is a very high-end delicacy with high nutritional value. It is reported in the literature that Flammulina velutipes contains higher protein, carbohydrates and crude fiber, but lower fat content, so it is a rare ...
