摘要: 建立了地骨皮中肉桂酸含量的高效液相色谱(HPLC)方法。采用ultimateC18柱,以水-乙腈(各含0.2%磷酸)为流动相,采用梯度洗脱,流速为0.5 mL/min,检测波长为278 nm,柱温为室温。肉桂酸在0.1~200 μg/mL之间线性关系良好,检出限和定量限分别为0.029 μg/mL和0.097 μg/mL,平均回收率大于92%。所建立的方法简单、快速、灵敏度高,能准确测定不同地骨皮样品中肉桂酸的含量。

Abstract: A HPLC method for determination of cinnamic acid in cortex lycii was developed.Separations were performed on an ultimate C18 column.Mobile phase consisted of water-acetonitrile(containing 0.2% phosphoric acid)and the flow rate was 0.5 mL/min.The detection wavelength was 278 nm and the column temperature was room temperature.Calibration curve for cinnamic acid was linear in the range of 0.1-200 μg/mL,limits of detection was 0.029 μg/mL and limits of quantification was 0.097 μg/mL.The average recoveries were >92%.The proposed method was simple,fast and sensitive,and could be used for accurate determination of cinnamic acid in cortex lycii.

Key words: HPLC, cortex lycii, cinnamic acid, UV
