The Thin-Layer Chromatographic Identification of Glycyrrhizae Radix and Its Use in Some Chinese Herbal Preparations

並列摘要


In this experiment we developed three TLC solvent systems for identifying Glycyrrhizae Radix and Its use in some Chinese herbal preparations. The solvent systems consisted of: n-Butanol-g. Acetic Acid-Water (7:1:2.5), n-Butanol-ammonia Water-Ethanol (5:2:1) and Chloroform-Methanol-Water (30:10:1). With these systems in the mobile phases, we could easily separate the constituents of Glycyrrhizae Radix in the herbal formulas of Ching-shang-fang-feng-tang (清上防風湯), Ma-shing-kan-shih-tang (麻杏甘石湯) and Chia-wei-hsiao-yao-san Consequently, using U. V. Light (254nm) or H2SO4/Ethanol (1:1) spray reagent clearly identified the spots showing the constituents of Glycyrrhizae Radix.
