摘要：Comparative pharmacokinetic profiles of glycyrrhetic acid (GA), glycyrrhizic acid (GL) and Gancao-Fuzi-Tang (KF) after oral administration of GL and KF were studied. Plasma samples taken from rats were acidified with acetic acid and GA was extracted with isopropanol–ethyl ether (1 : 1). Separation of GA was performed on a C₁₈ column with the detection wavelength set at 254 nm. The mobile phase was methanol–acetonitrile–water–acetic acid (58 : 18 : 24 : 1 v/v). The results showed that the mean residence time and area under the curve of GA in KF-administered rats were 27.6±1.5 h and 122.8±46.7 μg·h/ml respectively, which were significantly different from those in GL-administered rats (15.0±2.0 h and 40.9±9.6 μg·h/ml, respectively). The results suggest the increased effect of GA after oral administration of KF in comparison with GL.
