Objective :To establish a method for simultaneously determining geniposide and baicalin in Fangfengtongsheng pill. Method :A double wavelength RP-HPLC method was developed. The analysis was performed on a Hibar C18 column (4.6 mm×150 mm
5 μm)with gradient elution using acetoniterile-0.2% phosphoric acid
the flow rate was 1.0 mL·min-1. Geniposide and baicalin were detected at 240 nm and 278 nm respectively. The column temperature was 30 ℃. Result :The calibration curves of geniposide and baicalin showed good linearity in the ranges of 0.16-0.8 μg and 0.24-1.2 μg. The average recoveries were 96.0% and 100.7% with RSD of 2.96% and 2.86%. Conclusion :The method is simple
accurate and reproducible for simultaneous determining geniposide and baicalin in Fangfengtongsheng pill.
