中文摘要：

白芍和白术配伍起源于白术芍药散,临床上其生品配伍与制品配伍用于治疗不同的疾病。为了评价白芍和白术生品配伍和制品配伍之间的区别,本实验选取了简单,易行且灵敏度高的HPLC-DAD法同时测定其中9种活性成分的变化。线性关系良好,r2≥0.9992。检测限和定量限分别小于7.30μg/mL和11.53μg/m L。日内、日间精密度及重复性RSD值分别小于3.86%、2.71%和4.29%。稳定性RSD值小于3.64%。加样回收率在96.70%–102.10%,RSD值小于3.52%。建立的方法可以用于白芍和白术配伍内在质量的控制。

英文摘要：

The crude and processed Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pairs, originated from Bai-zhu-shao-yao-san, are used to treat different diseases clinically. In order to evaluate the crude and processed Paeoniae Radix-Atractylodis Macrocephalae Rhizoma herbal pairs, a simple, easy, and sensitive high-performance liquid chromatography coupled with diode array detectors was developed for simultaneous determination of nine bioactive components in the herbal pairs. The calibration curve exhibited good linearity（r2≥0.9992）. The LODs and LOQs were ≤7.30 and 11.53 μg/m L, respectively. The intra-, inter-day and repeatability RSD values of the nine compounds were less than 3.86%, 2.71%, and 4.29%, respectively. The RSD stability values were less than 3.64%. The recovery of the method was in the range of 96.70%–102.10%, with RSD values less than 3.52%. The developed method can be applied to the intrinsic quality control of crude and processed Paeoniae Radix-Atractylodis Macrocephalae Rhizoma herbal pairs.
