| Abstract: | The extraction conditions of polysaccharides from Flammulina velutipes off cuts by microwave and hot water were studied.The results showed that ratio of material to solvent,extraction temperature,extraction time of hot water method had significant effect on extraction yield and optimized conditions were 1:20,80℃,2.0h.Ratio of material to solvent,microwave power,extraction time of microwave method had significant effect on extraction yield and optimized conditions were 1:25,320W,80s.Under optimal conditions,the extraction yield was up to 13.68% and 13.80%,respectively.Microwave extraction was more efficient than hot water method and had a extensive future. |
