ABSTRACT
AIM: To establish the method for quality control of Gutongning Liniment(Herba Epimedii,Semen Strychni,Herba Ephedrae,etc.) METHODS: Herba Ephedrae,Radix Notoginseng,Ramulus Cinnamomi,Flos Caryophylli,Flos Daturae were identified by TLC,icariin content in Herba Epimedii and strychnine content in Semen Strychni were determined by HPLC. RESULTS: The identified characteristics of chromatography were distinct and the spots were clear.Icariin showed a good linear relationship at a range of 0.2-1.2 ?g,r=0.999 8.The(average) recovery was 10.3%,and RSD was 1.5%.Strychnine showed a good linear relationship at a range of 0.8-4.8 ?g,r=0.999 7.The average recovery was 99.17%,and RSD was 1.4%. CONCLUSION: The methods are accurate and reliable,and can be used to control the quality of this preparation effectively.
