Abstract

Objective:To establish an HPLC method for the determination of matfine in compound Kushensu.cap- sules.Methods:By HPLC using as Hypersil C_8 column(4.6 mm×150mm,5μm)and the mobile phase methanol- water-trietylamine(45:55:0.02),at a flow of 0.8 mL·min~(-1),and the UV detection at 220 nm.The column was 25 ℃ and the injection volume was 10μL.Results:The method was linear over the ragne of 10.7-161.0 μg·mL~(-1)(r =0.9999).The average recovery was 99.6%.Conclusion:The method is sensitive,simple and accurate.
