高效液相色谱法测定盆炎净片中咖啡酸的含量
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
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
