Abstract:Objective To establish a rapid, accurate and feasible HPLC method for simultaneous determination of calycosin-7-glucoside and chlorogenic acid in Yifeiqingjie soup. Methods The separation was carried out on a XterraRP18(5μm, 4.6mm×250mm) column, the mobile phase consisting of acetonirtile(A) -0.1%formic acid solution(B) at a flow rate of 1.2mL·min-1, with the column temperature of 40℃, the detection wavelength at 320nm. Results The calibration curve was liner over the range of 0.023~0.463μg (r=0.9999)for alycosin-7- glucoside; 0.042~0.836μg (r=0.9998) for chlorogenic. The average recovery of the two components was 101.52%(RSD=2.56%),100.39%(RSD=1.15%)respectively. Conclusion The method can be used for simultaneous determination of calycosin-7-glucoside and chlorogenic acid in Yifeiqingjie soup by our hospital traditional Chinese patent medicines, and it is applicative applicable for quality control of it.
