假臭草花挥发油的GC-MS分析

GC-MS Analysis of Essential Oil from the Flowers of Eupatorium catarium

采用水蒸气蒸馏法提取新鲜假臭草花的挥发油,利用气相色谱-质谱(GC-MS)联用技术分析该挥发油的化学成分。GC-MS共鉴定出35个化合物,占挥发油总量的81.82%。其主要成分为:1-甲基-5-亚甲基-8-(1-甲基乙基)-[s-(E,E)]-1,6-环癸二烯(31.98%)、石竹烯(11.75%)、己酸(6.25%)、3-甲基戊酸(6.10%)、α-毕澄茄醇(4.37%)、二叔丁基对羟基甲苯(3.98%)、4-乙烯基-2-甲氧基苯酚(3.48%)。

The essential oil from the flowers of Eupatorium catarium was extracted by steam distillation. The components of the essential oil were separated and identified by GC -MS. 35 components were identified and accounted for 81.82% of all the peak area. The major compositions were 1 -methyl-5 -methylene -8 - （1 -methylethyl） - [ s - （E, E） ] - 1,6 - cyclodecadiene （31.98% ）, caryophyllene （ 11.75 % ）, hexanoic acid （6. 25 % ）, 3 - methylpentanoic acid （ 6. 10% ）, α - cadinol （ 4. 37% ）, butylated hydroxytoluene （ 3.98% ）, and 2 - methoxy - 4 - vinylphenol （3.48%）.
