Abstract:
OBJECTIVE:To establish a RP-HPLC method for the determination of glycyrrhizic acid in sulfonamideglycyrrhiza mixture METHODS:Lichrosorb RPC18 analytical column was used The mobile phase was composed of methanol-(CH)4NH4OH(65∶35) The pH of the mobile phase was adjusted to 6 5 with 10% phosphoric acid Detection wavelength was 254nm RESULTS:Linearity was good in the range of 0 5～50?g/ml(r=0 9 996);the average recovery was 99 75%,RSD=1 87% CONCLUSION:The method is simple and convenient
