摘要：

A fast capillary zone electrophoresis (CZE) method has been developed for the determination of four flavonoids (liquiritin, licoisoflavone A, licochalconel A and calycosin) in Glycyrrhizae radix. After a series of optimization experiments, 100 mM borate buffer (pH 10.5), 30 kV applied voltage and 35 degreesC temperature were selected. The contents of four flavonoids in cultivated and wild crude drugs of Glyqrrhizzae radix with different growth periods from one to four years, collected from different areas were successfully determined within 8 min, with satisfactory repeatability and recovery.
