Abstract
In the present study, enzyme assisted extraction of Fructus Mori polysaccharides (FMPS) from F. mori using four kinds of enzymes and three compound enzymes were examined. Research found that glucose oxidase offered a better performance in enhancement of the extraction yields of FMPS, antioxidant and activate alcohol dehydrogenase activities. The glucose oxidase assisted extraction process was further optimized by using response surface method (RSM) to obtain maximum yield of crude FMPS. The results showed that optimized extraction conditions were ratio of enzyme amount 0.40%, enzyme treated time 38min, treated temperature 58°C and liquid–solid radio 11.0. Under these conditions, the mean experimental value of extraction yield (16.16±0.14%) corresponded well with the predicted values and increased 160% than none enzyme treated ones. Pharmacological verification tests showed that F. mori crude polysaccharides had good antioxidant and activate alcohol dehydrogenase activities in vitro.
