摘要
目的:鉴别归芍胶囊中的白芍和测定归芍胶囊中芍药苷的含量。方法:采用薄层色谱法鉴别白芍,高效液相色谱法测定芍药苷的含量,色谱柱为Shimadzu VP-ODS(4.6 mm×150 mm,5μm),以乙腈-0.1%磷酸溶液(14∶86)为流动相、检测波长230 nm、柱温35℃。结果:归芍胶囊中白芍的鉴别方法和芍药苷的含量测定方法专属性强,在40~320 mg/L内线性关系良好,平均回收率为99.94%(RSD=1.15%)。结论:薄层色谱法鉴别归芍胶囊中白芍,HPLC法测定芍药苷含量的方法简便、灵敏、准确。
Objective: To identify Radix paeoniae alba and to determin paeoniflorin content in Guishao capsules. Methods: Radix paeoniae alba was identified with thin layer chromatography (TLC). Paeoniflorin content was determined with high performance liquid chromatography (HPLC). The HPLC method was carried out on Shimadzu VP-ODS (4.6 mm × 150 mm,5μm)column using acetonitrile -0.1% phosphoric acid( 14: 86) as mobile phase Detection wavelength was 23Onto, and temperature of column was 35℃. Results: The identification method and the content determination method showed strong specificity. The calibration curve for paeoniflorin was linear in the range of 40 - 320 μg/ml. The average recovery was 99.94%, and RSI) was 1.15%. Conclusions: The methods are simple, sensitive and accurate.
