野生柳叶蜡梅茎挥发油化学成分的GC-MS分析

GC-MS Analysis of the Volatile Oils from the Stem of Wild Chimonanthus salicifolicus Hu

采用常压水蒸气蒸馏法提取柳叶蜡梅茎的挥发油,经GC-MS分析,从挥发油中鉴定出89种化合物,占总油量的84.98%。其中含量较高的成分为亚油酸(11.96%)、棕榈酸(11.38%)、(-)-β-杜松烯(5.10%)、桉叶油醇(4.89%)、大根香叶烯D(4.84%)、β-石竹烯(4.16%)、(1α,4aα,8aα)-1,2,4a,5,6,8a-六氢-4,7-二甲基-1-异丙基-萘(2.91%)、樟脑(2.43%)、石竹烯氧化物(2.23%)。

The volatile oils from the stem of Chimonanthus saslicifolicus Hu were extracted by water-steam distillation. Eighty-nine compounds, 84.98% of the total constituents, were identified fi＇om the oils by GC-MS analysis. The major constituents were linoleic acid （ 11.96% ）, palmitic acid （ 11.38% ）, （-） -β -cadinene （ 5.10% ）, eucalyptol （4.89%）, germacrene D （4.84%）, β-caryophyllene （4.16%）, 1,2,4a,5,6,8a-hexahydro-4,7-dimethyl-1- （1-methylethyl） - （1α,4aα, 8aα） -naphthalene （2.91%）, camphor （2.43%）, and caryophyllene oxide （2.23%）.
