Standardization of Licorice and TCM Formulations Using Eastern Blot Fingerprinting Analysis
Chromatographic fingerprinting of glycyrrhizin after injection of glycyrrhizin in rat serum by TLC stained by H2SO4 and eastern blotting. (a) TLC chromatographic fingerprinting stained by H2SO4. (b) Chromatographic fingerprinting by eastern blotting. GA, GC, and GG were glycyrrhetic acid, glycyrrhizin, and glycyrrhetic acid O-glucuronide, respectively. GC was detected until 1 hour after injection.
