Objective: To establish a new RP-HPLC method for simultaneous determination of geniposidic acid(GPA), chlorogenic acid(CA) and geniposide(GP) in Folium Cortex Eucommia. Methods: The chromatographic condition was Diamonsil-C18 column, the mobile phase consisting of CH3OH-H2O-HAc(17:83:1.5,PH=2.70);the flow rate was 1.0 ml/min;the detection wavelength was 237nm.Results : The standard geniposidic acid showed a good linear correlation within the concentration of 0.36 ~3.60μg,(r=0.9999),the average recovery of t...
