摘要:
[目的] 建立痤疮凝胶中黄芩苷、蒙花苷含量测定方法.[方法] 采用Acquity BEH C18(2.1 mm×50 mm,1.7 μm)色谱柱;以乙腈-0.1%甲酸(20:80)为流动相,流速0.3 mL/min,检测波长320 nm,柱温35 ℃. [结果] 黄芩苷和蒙花苷分别在3.767~75.34 μg和0.840 96~33.638 4 μg范围内线性关系良好,平均回收率分别为99.04%和97.42%(n=6);RSD分别为1.97%和1.81%.[结论] 该方法简便、准确、重现性良好,为痤疮凝胶的质量控制提供了理论依据.

Abstract:
[Objective] To establish a UPLC method for content determination of Baicalin and Linarin in Cuochuang Gel. [Methods] The column was Acquity BEH C18(2.1 mm×50 mm, 1.7 μm). The mobile phase consisted of a mixture acetonitrile-1%formic acid(20:80). The flow rate was 0.3 mL/min.The detection wavelength was 320 nm under 35 ℃. [Results] The calibration curves for baicalin and Linarin were linear in the ranges of 3.767~75.34 μg and 0.840 96~33.638 4 μg, and the average recovery was 99.04% and 97.42%(n=6), with RSD of 1.97% and 1.81%, respectively. [Conclusion] This method was simple, precise and repeatable, which can be used for quality control of Cuochuang Gel.
