[Content deternmination of glycyrrhizic acid in cortex glycyrrhizae].
Glycyrrhizic acid content in Fen Gancao (barked licorice root) and its rough bark (Cortex Glycyrrhizae) was determined by HPLC. The result showed that at least three unknown ingredients were detected in Cortex Glycyrrhizae which were not in Fen Gancao, and glycyrrhizic acid content in the Cortex Glycyrrhizae is higher than that in Fen Gancao. It suggests that Cortex Glycyrrhizae can be used as the material not only to extract glycyrrhizic acid but also for making additives. Furtheronore, Fen Gancao should be further studied in order to reveal the differences of pharmacological effects between Fen Gancao and Licorice Root (Radix Glycyrrhizae).
