Abstract

|
|
For the quality control of traditional herbal medicine, Galgeun tang, simultaneous determination of glycyrrhizin,
paeoniflorin, puerarin, 6-gingerol was established by using a high performance liquid chromatographic (HPLC) method with diode array detector. To separate five four constituents, DIONEX C18 column (5 μm, 120 A, 4.6 mm×150 mm) was used with gradient elution system of water and methanol. Validation of the chromatography method was evaluated by linearity, recovery, and precision test. Calibration curve of standard components showed excellent linearity (R2>0.9906). Limits of detection (LOD) and limits of quantification (LOQ) varied from 0.15 to 0.52μg/ml and 0.27 to 0.80 μg/ml, respectively. The relative standard deviations (RSDs) of data of the intra-day and inter-day experiments were less than 2.88% and 1.21%, respectively. The results of recovery test were ranged from 96.71 to 106.29% with RSD values 0.01-0.80%.
