摘  要:目的: 建立一种同时测定香蜂花药材中迷迭香酸、咖啡酸和咖啡酸乙酯含量的RP-HPLC分析法。方法: Hanbon Megres C18色谱柱 (4.6 mm×250 mm, 5 μm),流动相A为甲酸-乙腈-水(0.5:20:80),B为甲酸-甲醇-乙腈(0.5:40:60),梯度洗脱(0%-25 min,0%-45% B;25%-30 min,45%-100% B;30%-30.1 min,100%-0% B),流速1.0 mL·min-1,柱温35℃,检测波长330 nm。结果: 迷迭香酸、咖啡酸和咖啡酸乙酯分别在6.0-300.0,0.15-7.5 mg·L-1和0.15-7.5 mg·L-1线性关系良好,平均加样回收率(n=6)分别为99.48%,99.56%,101.7%。结论: 该方法准确,简便,适用于香蜂花药材的质量分析检验。Objective: The purpose of this study is to simultaneously determine the content of rosmarinic acid, caffeic acid and ethyl caffeate in Melissa officinalis by RP-HPLC. Method: Hanbon Megres C18 column (4.6 mm×250 mm, 5 μm) was adopted. The mobile phase consisted of formic acid-acetonitrile-water (0.5:20:80) and formic acid-methanol-acetonitrile (0.5:40:60) with gradient elution program(0-25 min, 0%-45% B;25-30 min, 45%-100% B;30-30.1 min,100%-0% B). The flow rate was 1.0 mL·min-1. The column temperature was set at 35℃ and the detection wavelength was 330 nm. Result: The linear ranges of rosmarinic acid, caffeic acid and ethyl caffeate were 6.0-300.0, 0.15-7.5 and 0.15-7.5 mg·L-1 respectively. The average recoveries(n=6) for the sample preparation of the markers were 99.48%,99.56%, and 101.7% respectively. Conclusion: The quantitative method for rosmarinic acid, caffeic acid and ethyl caffeate by HPLC can provide the basis for quality control of M. officinalis.
