摘要: 为了建立红栀骨科外洗散的质量控制方法。采用薄层色谱法对红栀骨科外洗散中的的大黄、黄柏、钩藤进行定性鉴别;采用高效液相法测定制剂中大黄素和大黄酚的含量。实验结果表明,薄层色谱中各味药的特征斑点清晰,且空白对照无干扰;大黄素在1.21~38.6 μg/mL范围内线性关系良好(r = 0.9999),平均加样回收率为99.6%,RSD为0.72%(n=6);大黄酚在2.53~80.8 μg/mL范围内线性关系良好(r = 0.9991),平均加样回收率为99.1%,RSD为0.64%(n=6)。本文所建立方法简便可行,结果准确可靠,重复性好,可有效控制红栀骨科外洗散的质量。

Abstract: The objective of study was to establish the quality standard for Hongzhiguke Powder.Rhei Radix et Rhizoma,Phellodendri Chinensis Cortex,Uncariae Ramulus Cumuncis were identified by ThinLayer chromatography (TLC).And the high performance liquid chromatography (HPLC) was applied for the determination of Emodin and Chrysophanol in the Hongzhiguke Powder.The experiment results showed that TLC spots were clear and the blank without interference. Emodin was linear with peak area score when its sample size was within the range of 1.2138.6 μg/mL (r =0.9999),the average recovery was 99.6% (RSD =0.72%,n=6);Chrysophanol was within the range of 2.5380.8 μg/mL (r =0.9991),the average recovery was 99.1% (RSD=0.64%,n=6).Finally,it was concluded that the established methods are simple,reliable and accurate,and can be applied as the quality control method of Hongzhiguke Powder.
