Determination of tetrandrine and fangchinoline in Qingshenjianfei Tablets by RP-HPLC / 中成药

AIM: To determine the contents of tetrandrine and fangchinoline in Qingshenjianfei Tablets by RP-HPLC. METHODS:In this method Zorbax C 18 column was used, and methanol—0.3%diethylamine (75∶25) as a mobile phase , the detection wavelength was at 242 nm. RESULTS:The recovery of tetrandrine was 103.65% and RSD was 1.59% .The recovery of fangchinoline was 97.11% and RSD was 1.91% (n=6). CONCLUSION: This method is simple,quick,reproducible and can be used for the quantitative analysis。
