Extraction of epimedium polysaccharide in enzyme method and its effects on reducing the free radical oxygen
Through single-factor experiment and orthogonal experiment of 3 factors and 3 levels,the conditions for extraction of polysaccharide from epimedium in enzyme method were optimized,and the same time,studied its effect on raducing the free radical oxygen;The result showed that:the optimized extraction conditions for polysaccharide form epimedium were 1.5 hours of extracting time,1.6% of the quantity of enzyme and 1:25 proportion of epimedium to solution;EPS could eliminate the hydroxyl free radical and the superoxide anion free radical.
