- 摘要:
- 为建立一种快速简便测定杜仲雄花中绿原酸含量的方法,采用 Agilent-C18色谱柱(4.6 mm×250.0 mm,5 μm),乙腈-0.4%醋酸(10∶90)等度洗脱,流速1.0 mL·min-1,柱温箱温度35 ℃,327 nm单波长检测,通过试验对该方法的稳定性、精密度等进行优化。结果表明,杜仲雄花绿原酸在测定范围内呈良好的线性关系(R2=0.999 8),平均回收率为97.30%。供试品溶液处理方法为环境友好型方法,能更好地减少环境污染,对实验人员安全性更高,且该方法具有较高的精密度和重复性,可用作杜仲雄花中绿原酸含量的测定。
- Abstract:
- In order to establish a rapid and simple method for the determination of chlorogenic acid in male flowers of Eucommia ulmoides, the chromatography was performed on Agilent-C18 column (4.6 mm×250.0 mm, 5 μm) with isometric elution of acetonitrile-0.4% acetic acid (10∶90) at the flow rate of 1.0 mL·min-1 at 35 ℃, single wavelength detection 327 nm. The stability and precision of the method were optimized through experiments. The results showed that the chlorogenic acid showed a good linear relationship (R2=0.999 8) and the average recovery was 97.30%. The treatment method of the test solution is environment-friendly, which can better reduce environmental pollution and protect the experimenters. The method has high precision and repeatability, and can be used as the determination of chlorogenic acid content in Eucommia male flowers.
