赤芍总苷质量标准研究

Study on quanlity control for total paeony glycoside

目的:制订赤芍总苷(TPG)制备工艺质量控制标准。方法:采用薄层色谱法(TLC)鉴别,紫外分光光度法(UV)定性检测芍药苷,用高效液相色谱法(HPLC)测定赤芍总苷中芍药苷含量。结果:TLC、UV定性方法简便、灵敏、专属性强;HPLC法准确、可靠、重现性好,平均回收率为100%,RSD为1.96%。结论:建立的方法可控制赤芍总苷质量。

Objective To set up the quanlity control for total paeony glycoside. Methods The paeonflorin in TPG was identified by TLC, qunlititive tested by UV, and quantititive determined by HPLC, the conditions of which were studied. Results Both the qunlititive testing methods of TLC and UV are easy and sensitive with high specialization; The quantititive determination of HPLC is accurate and steady with high fidelity, and the average recovery 100.1%, RSD 1.96%. Conclusion The conditions set up are able to control the quanlitv of TPG.
