摘要:

建立HPLC-DAD法同时测定金银花中10个酚酸 (咖啡酸、绿原酸、新绿原酸、隐绿原酸、3,5-O-双咖啡酰基奎宁酸、3,4-O-双咖啡酰基奎宁酸、4,5-O-双咖啡酰基奎宁酸、3,5-O-双咖啡酰基奎宁酸甲酯、3,4-O-双咖啡酰基奎宁酸甲酯、4,5-O-双咖啡酰基奎宁酸甲酯)的含量。采用100倍量50%乙醇超声30分钟提取制备样品, 选择C18色谱柱, 以乙腈-甲醇-0.1%甲酸水溶液为流动相进行梯度洗脱, 55分钟内完成10个酚酸类化合物的色谱分离; 10个酚酸类成分在测试范围内线性关系良好, r²>0.999, 其平均加样回收率均在98.57%-103.22%之间, RSD均小于3%。该方法准确, 灵敏度高, 重复性好, 可用于金银花药材中10个酚酸类成分的含量测定。

Abstract:

A reverse-phase HPLC-DAD method was developed for simultaneous quantification of ten phenolic acids (caffeic acid, chlorogenic acid, neochlorogenic acid, 4-O-caffeoylquinic acid, 3,4-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid, 4,5-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid methyl ester, 3,4-O-dicaffeoylquinic acid methyl ester, and 4,5-O-dicaffeoylquinic acid methyl ester) in the dried flower buds of Lonicera japonica Thunb. (Lonicerae Japonicae Flos; LJF). An optimal sample preparation method was established as 30-min ultrasonication with 100 times 50% (v/w) ethanol aqueous solution based on the orthogonal test results. The chromatographic separation of the ten phenolic acids was achieved with an AQ-C18 column (4.6 mm×250 mm, 5 µm) and a gradient elution of acetonitrile, methanol and 0.1% formic acid aqueous solution within 55 min. All calibration curves showed good linearity (r2>0.999) within test ranges. The average recoveries were in the range of 98.57%-103.22% with RSD less than 3%. The method developed was accurate, sensitive and reproducible for determination of ten phenolic acids in LJF.
