ABSTRACT
OBJECTIVE:
To develop a method for simultaneous determination of chlorogenic acid,geniposide,gentiopicro-side,ferulic acid,baicalin and ammonium glycyrrhizinate in Yindan pinggan capsule.METHODS:
HPLC method was adopted. The separation was performed on Wonda SilTM-C18 column with mobile phase consisting of acetonitrile-0.4% phosphoric acid solu-tion(gradient elution)at the flow rate of 0.8 mL/min. The detection wavelength were set at 325 nm(chlorogenic acid,ferulic ac-id),250 nm (geniposide,ammonium glycyrrhizinate) and 275 nm (gentiopicroside,baicalin). The column temperature was 30 ℃.RESULTS:
The linear ranges were 0.087-3.480 μg for chlorogenic acid(r=0.9998),0.201-8.040 μg for geniposide(r=0.9997),0.200-8.000 μg for gentiopicroside(r=0.9995),0.016-0.640 μg for ferulic acid(r=0.9999),0.105-4.200 μg for ba-icalin (r=0.9999) and 0.028-1.120 μg for ammonium glycyrrhizinate (r=0.9995),respectively. The limits of quantitation were 1.31,0.75,1.14,1.25,0.94,0.98 ng,and the limits of detection were 0.87,0.67,0.96,0.93,0.60,0.88 ng,respectively. RSDs of precision,stability and reproducibility tests were lower than 2.0%;recoveries were 99.9%-101.9%(RSD=0.7%,n=6), 98.7%-100.9%(RSD=0.9%,n=6),98.1%-101.5%(RSD=1.4%,n=6),98.5%-101.3%(RSD=1.3%,n=6),98.5%-101.7%(RSD=1.2%,n=6),98.2%-101.4%(RSD=1.2%,n=6),respectively.CONCLUSIONS:
The method is simple and accurate , can be used for simultaneous determination of chlorogenic acid,geniposide,gentiopicroside,ferulic acid,baicalin and ammonium glycyrrhizinate in Yindan pinggan capsule.
