摘要
用水蒸气蒸馏法提取松科植物黄枝油杉嫩枝中的精油,得油率为0.1%,采用毛细管气相色谱-质谱联用方法进行化学成分分析,首次鉴定出21种化合物,占总离子流出峰面积的89.59%。黄枝油杉嫩枝中水蒸气蒸馏系列精油的主要成分为萜烯类物质,主要有(-)-β-榄香烯(2.91%)、β-石竹烯(46.21%)、葎草烯(8.59%)、石竹烯氧化物(14.53%)和大根香叶烯(4.09%)。
An essential oil in a yied of 0, 1% was obtained from fresh twigs of Keteleeria calcarea by steam distillation. Twenty-one constituents were identified by GC-MS analysis for the first time, The identified constituents represent 89.59% of the peak area of the oil, Terpenes are major chemical constituents in the oil. The main compounds were （-）-β-elemene （2.91%）, β- caryophyllene （46.21%）, humulene （8.59%）, caryophyllene oxide （ 14.53% ） and germacrene （4.09%）.
