摘要

目的 :建立芍石护睛胶囊的质量标准。方法 :采用薄层色谱(TLC)对芍石护睛胶囊中的白芍、决明子进行定性鉴别;用高效液相法(HPLC)对制剂中的芍药苷的进行含量测定。色谱条件:用C18分析柱

以甲醇-水(27 ∶73)为流动相

检测波长230 nm

进样量10 μL。结果 :TLC中

供试品溶液色谱在与对照药材或对照品相应位置上出现相同颜色的斑点

阴性对照无干扰;HPLC中

芍药苷在 0.074~0.741 μg线性关系良好( r =0.999 95)

平均回收率100.7%

RSD2.0%( n =6)。结论: TLC呈现斑点清晰、特异性强

可用于芍石护睛胶囊的鉴别;芍药苷方法学研究简单、易行

可用于芍石护睛胶囊的质量控制。

Abstract

Objective: To establish the quality standard for Shaoshi Securing capsule. Method: Paeonia lactiflora and Catsia tora were identified by TLC. The content of paeoniflorin in Shaoshi Securing capsule was determined by HPLC. HPLC analytical method was carried out by using a C18 column and a mixture of methanol-water (27 ∶73) as the mobile phase. The detection wavelength was set at 230 nm. Result: Spots obtained from the test solutions had the same color in reference solution and medical material in the same location

and the bland solution had no interference. The calibration curve was linear in the range of 0.074-0.741 μg ( r =0.999 95). The average recovery of sample was 100.7% with RSD of 2.0% ( n =6). Precision of the analytical method was 1.1% ( n =6). Conclusion: In TLC the spots were very clear and specific to identify the herbal medicine in Shaoshi Securing Capsule. HPLC method is simple

quick

high precise and accurate for the quality control of the capsules.
