ABSTRACT
Objective To establish a HPLC method for the simultaneous determination of chlorogenic acid,liquiritigenin,cinnamic acid,and monoammonium glycyrrhetate in Tong Saimai Pellets.Methods A Zorbax 80A Extend-C18 column was used.The mobile phase consisted of acetonitrile and 0.1% phosphoric acid,and was used for gradient elution.Chlorogenic acid,liquiritigenin,cinnamic acid and monoammonium glycyrrhetate were determined by dual wavelength,?s=276nm,?R=590nm.Results The linear range of chlorogenic acid was 0.0505~1.6160 ?g,and r=0.9999;the average recovery was 98.17%,and sR=4.28%(N=6).The linear range of liquiritigenin was 0.0252~0.8064 ?g,and r=0.9999;the average recovery was 93.76%,and sR=1.94%(N=6).The linear range of cinnamic acid was 0.0111~0.3552?g,and r=0.9999;the average recovery was 98.25%,and sR =2.72%(N=6).The linear range of monoammonium glycyrrhetate was 0.3300~10.5600?g,and r=0.9999;the average recovery was 102.6%,and sR=1.93%(N=6).Conclusion This method is convenient,rapid and accurate,and it can be used for quality control of the production of Tong Saimai Pellets.
