RP-HPLC determination of ferulate acid in the compound angelica scinensis pian / 中国基层医药

ABSTRACT

Objective To determine ferulate acid in the compound angelica scinensis particle by RP-HPLC method.Methods The liquid chromatography was carried out using Zorbax C_ 18 (5?m,4.6mm?250mm),with detection wavelength at 320nm.The flow rate of mobile phase[5% acetic acid-methanol(75∶25)] was 1ml/min.Results The calibration curve was linear in the range of 0.0141～0.450mg/ml(r=0.9997,n=5).The average recoveries was 94.87%(RSD=0.5%).Conclusion The method establishied in this paper can be adopt for the compound angelica scinensis particle.This method is simple,accurate,reliable and reproducible.
