ABSTRACT
Objective To establish the HPLC determination method of chlorogenic acid for developing the quality standard of Yinqiao Jiedu Oral Liquid.Methods HPLC method was performed on an E.Merck LiChrospher 100RP-18 column(250 mm? 4 mm,5 ? m).The mobile phase consisted of acetonitrle and o.4 % phosphoric acid(10100).The flow rate was 1.0 mL/min,column temperature was 30 ℃,and the detection wavelength was 327 nm.Results Chlorogenic acid was linear at the range of 0.12~ 0.63 ? g(r=0.999 6),the average recovery was 96.68 %,and RSD was 1.56 % .Conclusion This method is accurate,reliable,reproducible,and can provide evidence for the quality control of Yinqiao Jiedu Oral Liquid.
