Abstract:

To establish a preparation method and quality standard for the Wenxin capsule． MethodsThinlayer chromatography (TLC) was employed to identify Radix et Rhizoma Nardostachyos， Radix Codonopsis and Radix et Rhizoma Notoginseng． The contents of Ginsenoside Rg1  and Notoginsenoside R1 were determined by high pressure liquid chromatography． ResultsQuality control showed that identification by TLC was distinct and highly specific． The average recovery of Ginsenoside Rg1  was 96.07% with RSD at 0.33% and  Notoginsenoside R1 was 95.98% with RSD at 0.56%． ConclusionHigh pressure liquid chromatography is easy，accurate and reproducible and can be used for quality control of this preparation．
