| Abstract: | Objective:To confirm the optimum extraction of the total saponins from Rhizoma Dioscoreae Zingiberensis.Method: Optimum conditions were established by orthogonal design test.The extract was hydrolyzed by 3% hydrochloric acid,the disogenin was separated by petroleum ether and contents were determined by colofimetry.Result:The best processing conditions were as follows:the samples were broken to thick granules,refluxed with 8 times amount of 80% alcohol and for 2 times(2 h,1h).Conclusion:The pro- eessing method is simple.It can be used for production in industry. |
