In reversed phase high performance liquid chromatography, the baseline drift and the artifactual bands in blank gradient elution might result form the impurities from both weak aqueous and strong organic solvent.

在反相高效液相色谱中，空白梯度基线的漂移和杂质峰，可能由含水溶剂和有机溶剂中杂质所引起的。

Methods: The HPLC method was used, chromatography conditions were C 18V column, binary solvent-delivery gradient elution, diode-array detector, internal standard ( paeoniflorin) were taken as the criteria for quality control.

方法：HPLC法；采用C18V反相色谱柱，二元梯度洗脱，二极管阵列检测器，以芍药苷为内标作为相对标准。
