消肿止痛膏质量标准研究

Study on Quality Standards of Xiaozhongzhitong Mastic

目的探讨消肿止痛膏的质量标准。方法采用薄层色谱(TLC)法对处方中的黄柏、大黄、三七进行定性鉴别;采用高效液相色谱(HPLC)法测定栀子苷的含量。结果用TLC法能鉴别出黄柏、大黄、三七;HPLC法平均回收率为98.5%,RSD为1.35%,栀子苷在0.0672～1.68μg范围内呈良好的线性关系(r=0.99996)。结论该方法操作简单,准确可靠,重现性好,可作为消肿止痛膏的质量控制方法。

Objective To study the quality standard for controlling the quality of Xiaozhongzhitong mastic. Methods Cortex Phellodendri Chinensis, Radix Et Rhizoma Rhei and Radix Et Rhizoma Notoginseng were identified by TLC, and the content of geniposide was determined by HPLC. Results Cortex Phellodendri Chinensis, Radix Et Rhizoma Rhei and Radix Et Rhizoma Notoginseng could be identified by TLC. The determination of geniposide showed a good linear relationship at a range of 0. 0672 - 1.68 μg（ r = 0. 999 96）. The mean recovery rate was 98.5%, RSD was 1.35%. Conclusion The method is simple, accurate, reliable and repeatable. It can be used in the quality control of Xiaozhongzhitong mastic.
