Abstract : A high performance liquid chromatography method was studied for determination of 18 b-glycyrrhetinic acid in Glycyrrhiza glabra L. )licorice( extract. The operating condition were C-18 reversed phase column )VP-ODS, )250أ4.6 mm, 5 mm(( at room temperature, acetonitril/phosphoric acid )3/1( as mobile phase, at flow rate of 0.6ml/min )0-8min(, 0.4ml/ min )8-20min( and UV detection at 230 nm. The recoveries were percent99.60-percent102.81 with relative standard deviation between percent0.01-percent1.58. The relative standard deviation of the repeatability test was percent2.96. The method is simple, rapid, safe, accurate, economical and useful for standardization of the licorice products.
