摘要
目的探讨川芎药材的鉴别方法,完善川芎药材的质量标准。方法用薄层色谱法鉴别川芎药材;以高效液相色谱法测定阿魏酸的含量。选用Agilent Eclipse XDB-C18柱(4.6mm×150mm,5μm),流动相为甲醇-1%冰醋酸溶液(21∶79),流速为1.0mL/min,检测波长为320nm。结果薄层色谱中斑点清晰,易于识别。高效液相色谱法精密度、重现性良好;阿魏酸在0.0425～0.3825μg范围内有较好的线性关系,平均回收率为97.10%(RSD=1.31%)。结论本法可有效控制川芎药材的质量。
Objectiv To improve the quality standard for Chuanxiong by studing the method of discriminating Chuanxiong. Methods Chuanxiong was identified by TLC. The content of ferulic acid in Chuanxiong was determine by HPLC, The Agilent Eclipse XDB-C18（4,6 mm×150 mm, 5 μm） was used, mobile phase was methanol-1% acetic acid solution （21 ： 79）, flow rate was 1.0 mL/min, detection wavelength was 320 nm. Results The TLC spots developed were fairly and simply identical. HPLC was accurate and reproducible. Ferulic acid showed a good liner relationship at range of 0.042 5～0.382 5 ×g, the average recovery was 97.10% （RSD=1.31%）. Conclusion These methods can be used to control the quality of Chuanxiong effectively.
