摘要:

的分析不同产地及种属罗布麻叶挥发油的化学成分。方法用水蒸气蒸馏法提取罗布麻叶挥发油,以气相色谱-质谱联用技术进行挥发油的化学成分分析。结果不同产地及种属罗布麻叶挥发油的化学成分有较大的不同。运城红麻中含有较多的烯、酮、酸,占挥发油含量的31.78%,并首次从中得到7-甲基-6,9-二烯-氧杂环十二烷-2-酮、3-叔丁基-4-羟基茴香醚、高胡椒乙胺、芴、菲及叶绿醇;东北红麻中含有较多的酸、酮,占挥发油含量的28.44%,首次从中得到2-甲基-6-对甲基苯基-2-庚烯、肉豆蔻醛;陕西红麻中含有较多的烯、酮,占挥发油含量的39.89%,首次从中得到长叶烯、柏木烯、香叶基丙酮、棕榈酸及其甲酯;运城白麻中含有较多的长链碳原子饱和烃类物质,占挥发油含量的19.88%,此外含有占挥发油18.03%的酮类物质。结论不同产地采集的生药材,其挥发性物质的含量和成分有一定的差别,罗布麻的挥发性成分应分别加以研究利用。

Abstract:

OBJECTIVE To study the constituents of volatile oil in Apocynum venetum L. from various habitats and different species. METHODSThe volatile oil was extracted by water distillation method and analyzed by GC-MS. RESULTSThe constituents of volatile oil in Apocynum venetum L. from various habitats and different species have obvious differences. The main constituents from Yuncheng Apocynum venetum L. represented 31.78% of the total oil,oxacyclododeca-6, 9-dien-2-one, 7-methyl,fluorene,phytol, 3-tertbutyl-4-hydroxyanisole,piperonylamine,phenanthrene were found firstly.The main constituents of the volatile oils from Dongbei Apocynum venetum L.found firstly were benzene,1-(1,5-dimethyl-4-hexenyl)-4-methyl,tetradecanal.The main constituents of the volatile oil from Shanxi Apocynum venetum L. represented 39.89%,longifolene,cedrene,5,9-undecadien-2-one,6,10-dimethyl-(E),n-Hexadecanoic acid,hexadecanoic acid,methyl ester were found for the first time.Lastly the main constituents from Yuncheng Pocynum hendersonii W.represented 19.88% of the total oil,most of them were saturated hydrocarbons.CONCLUSIONEssential substances are different in quantity and quality in various habitats and different species. The main constituents of the volatile oil from Apocynum venetum L. should be made use of differently.
