Influence of the Different Combination of Huangqi on the Quantity of Huangqi Playodin in Huangqi Guizhi Wuwu Tang
Abstract:ObjectiveTo study the influence of the factors to the extraction rate of saponins from hot water extraction of herb composition in HuangQi Guizhi WuWu Tang containing Ramulus Cinnamomi, Raidix Paeoniae Alba, Fructrs Jujubae, Rhizoma Zingiberis Recens and Radix Astragali and to decide the facts and the interacts among factors.MethodsThe influence factors were explored with orthogonal design method and the astragalus-freed samples in different formula as control. The content was detected by UV-Vis spectrophotometer.ResultsWhen considered with single factor, Raidix Paeoniae Alba affected on the extraction rate of tragaloside most, followed by Fructrs Jujubae and Ramulus Cinnamomi. In the interact among factors, the concordinated action by Rhizoma Zingiberis Recens and Fructrs Jujubae affected on the extraction rate of tragaloside most, then Raidix Paeoniae Alba and Ramulus Cinnamomi, Raidix Paeoniae Alba and Rhizoma Zingiberis Recens, Raidix Paeoniae Alba and Fructrs Jujubae. ConclusionStatistic analysis showed that only the concordinated action between Rhizoma Zingiberis Recens and Fructrs Jujubae obviously affected the extraction rate of tragaloside (P<0.05).
