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 determination of caffeic acid in PYJP
