摘要: 建立同时测定忍冬藤中9种活性成分(新绿原酸、绿原酸、隐绿原酸、马钱苷、芦丁、木犀草苷、异绿原酸B、异绿原酸A、异绿原酸C)含量的HPLC法。HPLC分析条件:色谱柱ZORBAX SB-C18(4.6 mm × 250 mm,5 μm),流动相0.2%甲酸水-乙腈梯度洗脱,流速1 mL/min,柱温30 ℃,检测波长325 nm(新绿原酸、绿原酸、隐绿原酸、异绿原酸B、异绿原酸A、异绿原酸C),350 nm(芦丁、木犀草苷),254 nm(马钱苷)。实验结果显示9种待测成分分离度良好;各成分质量浓度与峰面积在测定范围内均呈良好线性关系(R2≧0.9996),新绿原酸、绿原酸、隐绿原酸、马钱苷、芦丁、木犀草苷、异绿原酸A、异绿原酸B、异绿原酸C的平均回收率(RSD)分别为10270%(2.54%)、100.05%(3.29%)、102.11%(1.47%)、100.04%(1.32%)、101.72%(0.51%)、100.58%(0.51%)、101.88%(1.02%)、100.55%(0.27%)、101.39%(1.29%)。HPLC法灵敏、准确、可靠、重复性好,可用于忍冬藤药材的质量评价。

Abstract: The aim of this study was to establish a HPLC detection method for the simultaneous determination of 9 bioactive components (neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,loganin,rutin,cynaroside,isochlorogenic acid B,isochlorogenic acid A,isochlorogenic acid C) in Lonicerae japonicae Caulis.The chromatographic separation was carried out on a ZORBAX SB-C18 (4.6 mm × 250 mm,5 μm) column with gradient elution of acetonitrile and 0.2% formic acid in water at a flow rate of 1 mL/min and column temperature was 30 ℃.The detection wavelength were set at 254 nm for loganin,325 nm for neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,caffeic acid,isochlorogenic acid B,isochlorogenic acid A,isochlorogenic acid C,and 350 nm for rutin,cynaroside,respectively.Excellent chromatographic separation was achieved with good linearity (R2≧0.9995) within the studied concentration ranges.The average recovery rates (RSD) of neochlorogenic acid,chlorogenic acid,cryptochlorogenic acid,loganin,rutin,cynaroside,isochlorogenic acid B,isochlorogenic acid A,isochlorogenic acid C were 102.70% (2.54%),100.05% (329%),102.11 (1.47%),100.04% (1.32%),101.72% (0.51%),100.58% (0.51%),101.88% (1.02%), 100.55% (0.27%),101.39% (1.29%),respectively.The established method was of high sensitivity and good reproducibility,and it can be used for quality control of L.japonicae.
