摘 要:目的:应用高效液相色谱法测定盆炎净片(PYJP)中咖啡酸的含量。方法:采用C18色谱柱(4.6 mm×250 mm,5μm),甲醇-磷酸盐缓冲液(23∶77)为流动相,流速1.0 mL.min-1,检测波长323 nm。结果:咖啡酸在0.072 96~0.437 76μg进样量与峰面积呈良好的线性关系(r=0.999 9),平均加样回收率为99.10%,RSD 1.22%(n=5)。结论:该方法测定结果准确、灵敏、重复性好。Objective:To develop an HPLC method for determination of the content of caffeic acid in PYJP.Method:An C18 column was used as the chromatographic column.The mobile phase consisted of methanol-phosphate buffer(23∶ 77),the flow rate was 1.0 mL.min-1.The UV detection wavelength was at 323 nm.Result:There was a good linear relationship between the concentration of caffeic acid and peak area value when the concentrations of caffeic acid was within the range of 0.072 96-0.437 76 μg(r = 0.999 9).The average recovery was 99.10%,RSD 1.22%(n = 5).Conclusion:The method was accurate,sensitive,reproducible and may be used in the determina-tion of caffeic acid in PYJP
