| Abstract: | To optimize the extraction process of total saponin from Polygonum cuspidatum stem,the content of Resveratrol was used as the main evaluation index.The optimum process was obtained through the result of orthogonal test.The optimum conditions of concentration of ethanol,extracting time,solid to liquid ratio and extracting temperature were 60%,2 hour,115 and 80℃.The result of process verification showed that the optimum process was stable and reliable.The study provided scientific basis for the development of Polygonum cuspidatum. |
