Figure 3: Eastern blotting profile of glycyrrhizin in rat serum after injection of glycyrrhizin (a) TLC of rat-serum-injected glycyrrhizin TLC was developed with n-BuOH-H2O-AcOH (7 : 2 : 1). Spots were detected by 10% H2SO4. (b) Eastern blotting of rat-serum-injected glycyrrhizin; the band of glycyrrhizin was detected until 1 h after injection. GA: glycyhrrhetinic acid, GC: glycyrrhizin, and GG: glycyrrhetinic acid monoglucuronide.
