Studies on Licorice in Drug Preparations(I) Determination of Glycyrrhizin and Glycyrrhetinic acid by HPLC.
생약중의 감초에 관한 연구(I) HPLC에 의한 Glycyrrhizin 및 Glycyrrhetinic acid의 정량
Abstract
Glycyrrhizin (GA) content in licorice was determined by a couple of methods using HPLC, respectively. In Method(I), GA content itself was determined from the licorice aqueous extract, while in Method (II) glycyrrhetinic acid (GHeA ; the aglicone of GA) content corresponding to the quantity of GA was measured from the chloroform extract of the hydrolyzed product of licorice aqueous extract. A reverse phase column Hibar Lichrosorb RP-18 (E. Merck) was used as the stationary phase. As the mobile phase MeOH:
