摘    要:目的:建立高效液相色谱-电喷雾多级质谱法(HPLC-DAD-ESI-MSn),鉴定鸢尾根茎中的黄酮和酚酸类成分。方法:利用样品的色谱的保留时间以及多级质谱分析,对其中的黄酮和酚酸类成分的结构进行了鉴定。结果:十个黄酮分别鉴定为鸢尾苷元7-O-β-葡萄糖-4'-O-β-葡萄糖双糖苷(3),鸢尾苷(5),鸢尾新苷B(6),鸢尾新苷A(7),野鸢尾苷(8),染料木素(11),鸢尾苷元(12),鸢尾甲黄素A(14),鸢尾甲黄素B(16)和野鸢尾苷元(17)。两个二氢黄酮,一个黄酮醇和一个二氢黄酮醇暂时分别鉴定为橙皮素(9),5,7,3'-三羟基-6,4'-二甲氧基二氢黄酮(10),鼠李柠檬素(13)和二氢山奈酚(15)。此外三个酚酸类成分为草夹竹桃双糖苷(1),草夹竹桃苷(2)和夹竹桃麻素(4)。结论:所建立的高效液相色谱-电喷雾多级质谱法可以用于快速鉴定鸢尾根茎中的活性成分。并首次在该植物中鉴定出橙皮素(9)、5,7,3'-三羟基-6,4'-二甲氧基二氢黄酮(10)。

Abstract:AIM:To develop high performance liquid chromatography combined with photodiode-array detection and electrospray ionization multiple-stage mass spectrometry(HPLC-DAD-ESI-MSn) for the analysis and identification of flavonoids and phenolic acids in the rhizome of Iris tectorum Maxim..METHOD:The structures of flavonoids and phenolic acids were identified by chromatographic retention times,UV spectra as well as ESI-MSn spectra.RESULTS:Ten isoflavones were identified as tectorigenin-7-O-β-glucosyl-4'-O-β-glucoside(3),tectoridin(5),iristectorin B(6),iristectorin A(7),iridin(8),genistein(11),tectorigenin(12),iristectorigenin A(14),iristectorigenin B(16),i and rigenin(17).Two flavanones,one flavonol and one flavanonol were tentatively identified as hesperetin(9),5,7,3'-trihydroxy-6,4'-dimethoxyflavanone(10),rhamnocitrin(13) and dihydrokaempferide(15),respectively.The three phenolic acids were tectoruside(1),androsin(2) and apocynin(4).CONCLUSION:The developed simple and rapid method is useful to rapidly identify the bioactive constituents in the rhizome of Iris tectorum.Two flavanones,hesperetin(9) and 5,7,3'-trihydroxy-6,4'-dimethoxyflavanone(10) were identified from this species for the first time.
Keywords:Iris tectorum Maxim    HPLC-DAD-ESI-MSn  Flavonoids  Phenolic acids
