Abstract

The aim of this work was to employ optimization strategy based on statistical experimental designs to enhance the polysaccharides extraction yield from Gynostemma pentaphyllum. The effects of three independent variables on the polysaccharides extraction yield were investigated and the optimal conditions were evaluated by means of Box-Behnken design. The optimal conditions are as follows: ratio of water to raw material 31, extraction temperature 90 and extraction time 2.5h. Under these conditions, the polysaccharides yield is 3.80±0.15%(N=5) , which is agreed closely with the predicted yield value.
