ABSTRACT
OBJECTIVE:
To establish a method for the content determination of chlorogenic acid,rutin,phillyrin,quercetin and glycyrrhizic acid in Sangju ganmao granules.METHODS:
HPLC method was adopted. The determination was performed on WondasilTM-C18 column with mobile phase consisted of acetonitrile-0.4% phosphoric acid solution(gradient elution)at the flow rate of 0.8 mL/min. The column temperature was set at 30 ℃,and the detection wavelength was set at 254 nm. The sample size was 5 μL.RESULTS:
The linear range of chlorogenic acid,rutin,phillyrin,quercetin and glycyrrhizic acid were 0.014-0.560 μg (r=0.999 2),0.022-0.880 μg(r=0.999 6),0.010-0.400 μg(r=0.999 9),0.016-0.640 μg(r=0.999 9),0.011-0.440 μg(r=0.999 1), respectively. The limits of quantitation were 0.752,0.647,0.483,0.372,0.242 mg/L;the limits of detection were 0.253,0.185, 0.157,0.162,0.098 mg/L. RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The average recoveries were 97.4%-100.9%(RSD=1.4%,n=6),95.7%-99.0%(RSD=1.1%,n=6),95.1%-98.1%(RSD=1.3%,n=6),96.4%-99.8%(RSD=1.4%,n=6),97.8%-100.4%(RSD=1.0%,n=6),respectively.CONCLUSIONS:
The method is simple,precise,stable and reproducible,and can be used for simultaneous determination of chlorogenic acid,rutin,phillyrin,quercetin and glycyrrhizic acid in Sangju ganmao granules.
