Objective:To investigate the optimum extraction process of the total saponins of Gynostemma pentaphyllum; Methods:Orthogonal test was used, in which the output of the total saponins was regarded as an examin-ation target and the influence of four factors in the extraction of effective substance were investigate. The four factors were the concentration of ethanol, ratio of material to liquid, the time of extraction and the mumber of extraction; Results:The optimum extraction process of the total saponins of Gynostemma pentaphyllum was established as follows: the concentration of ethanol 70%, ratio of material to liquid1∶6, extraction time 1 h, 2 times.
