南美蟛蜞菊叶挥发油化学成分分析

采用水蒸汽蒸馏法提取南美蟛蜞菊叶的挥发油,应用气相色谱-质谱联用(GC-MS)的方法对其挥发油的化学成分进行测试分析,运用气相色谱峰面积归一法确定各个成分的相对百分含量。共分离鉴定出56个化学成分,主要成分为:α-蒎烯(30.35%)、a-水芹烯(16.67%)、D-柠檬烯(15.92%)、1,2,3,4,4a,5,6,8a-八氢-7-甲基-4-亚甲基-1-(1-甲基乙基)-萘(4.71%)、1-乙烯基-1-甲基-2-(1-甲基乙烯基)-4-(1-乙缩醛甲基)-环己烷(4.08%)、石竹烯(3.45%)、1-甲基-2-(1-甲基乙基)-苯(3.37%)等。

Compositions of the Volatile Oil from Leaves of Wedelia trilobata Hitchc.

The volatile oil from leaves of Wedelia trilobata (L.) A. S. Hitche was obtained by steam distillation. Components of the volatile oil were analyzed by GC - MS, and their relative contents were determined by area normalization. Fifty six chemical compounds were identified. The major components were α - pinene (30.35%), α - phellandrene (16.67%), D-limonene (15.92%), 1, 2, 3, 4, 4a, 5, 6, 8a-octahydro-7-methyl-4-methylene-1-(1-methylethyl)-Naphthalene (4.71%), 1-thenyL~(-1)-methy-2-(1-methylethenyl)-4-(1-methylethyliden)-cyclohexane (4.08%), caryophhyllene (3.45%), 1-methyl-2-(1-methylethyl)-benzene (3.37%), etc.
