Extraction of Polysaccharide from Hippophae fhamnoides L.by Microwave Synergistically Assisted Technique

The study aims to optimize the microwave synergistic extraction technique of polysaccharide from Hippophae flwmnoides L.The effects of extraction time,power of microwave and the ratio of liquid to solid on the yield of polysaccharide are explored by single-factor experiment,and the optimum technique parameter is determined by the orthogonal test.And then the extraction effect of the method is compared with that of water extraction,enzyme method extraction and ultrasonic assisted extraction.The optimal technique conditions for the microwave synergistic extraction are:the extraction time 45 min,power of microwave is 100 W and the ratio of solid to liquid 1:30.Under these conditions,the highest yield of polysaccharide from Hippophae flwmnoides L.is 7.36%.
