Abstract: This was the first time that High Performance Capillary Electrophoresis was used to determine the glycyrrihizin acid content in the plant Glycyrrhiza Uralensis. Ficsh. The capillary used was 75 μm i.d.and 62cm in length. UV detection was set at 252nm.The calibration curve showed good linearity. The recovery of glycyrrihizin acid ranged from 96%~99%.This method is simple, rapid and reliable.

Key words: high performance capillary electrophoresis, Glycyrrhiza uralensis.glycyrrihizn Acid
