【Abstract】 Objective Studies on quality control of Zhipiantong granules.Methods The content of paeoniflorin was determined by RP-HPLC. Shimpack CLC-ODS column (6.0 mm×150 mm,5 μm)was used with a mobile phase of methanol-0.05 mol/L KH2PO4 solution-Acetic Acid-Isopropanol (67:173:4:4)and detected at 230 nm.The flow rate was 1.0ml/min.Results The Range of linearity is 0.2~2.0 μg paeoniflorin (r=0.999 9).The theoretical plate number is 6 000.The average recovery is 100.8%.Conclusion The established method is simple ,reliable and suitable for the usual quality control method of Zhipiantong granules ......
