摘要: 本实验建立了UHPLC同时测定不同产地金银花中绿原酸、芦丁、木犀草苷、异绿原酸A、异绿原酸B、异绿原酸C含量的分析方法。采用Agilent 1290超高效液相色谱系统,Agilent ZORBAX RH C18 色谱柱(50 mm×2.1 mm,1.8 μm),流动相为乙腈-0.2%磷酸水,以0.2 mL/min的流速进行梯度洗脱,柱温30 ℃,检测波长350 nm。结果表明在该色谱条件下,金银花的6种有效成分在8 min内可达到基线分离。方法的加样回收率为96.88%~99.16%,相对标准偏差为0.23%~1.06%。UHPLC法分析速度快,重复性好,结果准确,可用于金银花中绿原酸、芦丁、木犀草苷、异绿原酸A、异绿原酸B、异绿原酸C的含量测定。

Abstract: To establish an UHPLC method for simultaneous determination of six compounds,namely chlorogenic acid,rutin,luteoloside,3,5-O-dicaffeoylquinic acid, 3,4-O-dicaffeoylquinic acid and 4,5-O-dicaffeoylquinic acid in Lonicera japonica Thunb from different areas.The chromatographic separation was performed on an Agilent ZORBAX RH C18 (50 mm × 2.1 mm,1.8 μm) column with gradient elution.The flow rate was 0.2 mL/min.The column temperature was 30 oC.The detection wavelength was 350 nm.The recoveries of rutin,luteoloside and four kinds of organic acids were 96.88%-99.16%,and the relative standard deviations were 0.23%-1.06%.The developed UHPLC method was reproducible,accurate and efficient.It can be used for the simultaneous detection and determination of chlorogenic acid,rutin,luteoloside,3,5-O-dicaffeoylquinic acid,3,4-O-dicaffeoylquinic acid,4,5-O-dicaffeoylquinic acid in L.japonica.
