【Abstract】 A HPLC method for determination of paeoniflorin in Siwu tablets was established. A Diamonsil C18column was used with the mobile phase of methanol -0.05mol/L KH2PO4 solution(40∶60), at the detection wavelength of230nm. The flow rate was 1.0ml/min. The average recovery was 99.4% with RSD of 1.81%. 更多还原 【关键词】 四物片; 芍药苷; 高效液相色谱; 测定; 【Key words】 Siwu tablets; paeoniflorin; HPLC; determination;
