황련해독탕 중 3종 생리활성 물질의 HPLC-DAD 동시 정량분석법 확립

초록

In this study, a high performance liquid chromatography-diode array detector method was established, for simultaneous determination of three compounds, berberine, palmatine and geniposide in Hwangryunhaedok-tang, To develop and validate method, C_18 column (5 μm, 4.6 mm×250 mm) was used with gradient mobile phase, water containing 0.1% trifluoroacetic acid (TFA) and MeOH at the column temperature of 30℃. UV wavelength was set at 230 and 280 nm. Validation of the chromatography method was evaluated by linearity, precision and accuracy test. Calibration curve of standard components showed good linearity (R^2>0.9999). The limits of detection (LOD) and limits of quantification (LOQ) varied from 0.05 to 0.17 μg/ml and 0.15 to 0.53 μg/ml, respectively. The relative standard deviations (RSDs) data of intra-day and inter-day test were in less than 2.99% and 1.90%, respectively. The results of the accuracy test were in the range of 98.36 to 102.52% with RSDs values 0.32 to 1.98%. The results of validation indicated that this method was a very accurate and sensitive assay.
