摘　　要：利用广泛靶向代谢组学方法对云南香格里拉西南鸢尾(Iris bulleyana Dykes)地上部分的化合物类型和相对含量进行了详细分析。结果表明:在西南鸢尾地上部分共检测到11大类431种化合物,其中,黄酮类化合物最多(116种),占比26.9%;脂质类、氨基酸及其衍生物、酚酸类、核苷酸及其衍生物、有机酸类、生物碱类以及木脂素和香豆素类化合物分别有58、52、40、36、34、24和20种,占比分别为13.4%、12.1%、9.3%、8.4%、7.9%、5.6%和4.6%;鞣质类和萜类化合物较少,分别只有6和2种,占比各为1.4%和0.5%;其他化合物相对较多(43种),占比10.0%。总体来看,黄酮类化合物是西南鸢尾地上部分的主要化学成分,且西南鸢尾地上部分的很多化合物具有重要的药用价值,开发利用前景广阔。值得注意的是,西南鸢尾地上部分还含有葫芦巴碱、6-脱氧荞麦碱和色胺等生物碱类成分,推测这些生物碱类成分可能是中甸牦牛(Bos grunniens Linn.)拒食营养生长期西南鸢尾的主要原因。Compound types and relative contents in above-ground part of Iris bulleyana Dykes from Shangri-La of Yunnan Province were analyzed in detail by using widely targeted metabolomic method.The results show that 431 compounds of 11 types are detected in above-ground part of I.bulleyana,in which,the number of flavonoids is the most(116),accounting for 26.9%;the numbers of lipids,amino acids and their derivatives,phenolic acids,nucleotides and their derivatives,organic acids,alkaloids,and lignans and coumarins are 58,52,40,36,34,24,and 20,accounting for 13.4%,12.1%,9.3%,8.4%,7.9%,5.6%,and 4.6%,respectively;the numbers of tannins and terpenoids are relatively few,which are only 6 and 2,accounting for 1.4%and 0.5%,respectively;other compounds are relatively more(43),accounting for 10.0%.Overall,flavonoids are the main chemical components in above-ground part of I.bulleyana,and many compounds in above-ground part of I.bulleyana have important medicinal values,which have a great development and utilization prospect.Notably,there are alkaloids in above-ground part of I.bulleyana,such as trigonelline,6-deoxyfagomine,and tryptamine,and these alkaloids may be the main reason for food refusal of Bos grunniens Linn.against I.bulleyana at vegetative growth phase.
