Abstract
Objective To establish the quality standard of Fufang-Shiwu-Zhixue powder. Methods The microscopical identification was adopted to analyze charred typha pollen and cuttlebone. TLC was used to identity rhubarb and radix notoginseng. UV-HPLC was used to determine the contents of notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1. Results Microscopic identifications shower the characteristics of harred typha pollen and cuttlebone. The identified characteristics of rhubarb and radix notoginseng by TLC were distinct and the spots were clear. Notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1 showed good linearity in the range of 0.16-1.58 µg (r=0.999 8), 0.58-5.81 µg (r=0.9999), 0.33-3.29 µg (r=1.000 0), respervtively.The average recoveries were 98.51% (RSD=1.81%), 97.80% (RSD=2.04%), 98.22% (RSD=1.45%). Conclusions The method is accurate, simple and repeatable, which could be used for the quality control of Fufang-Shiwu-Zhixue powder.
