摘要: 采集不同海拔的细叶亚菊地上部分为原料,采用水蒸馏法提取挥发油。用GC-MS对挥发油进行化学成分分析,通过SPSS 22.0统计软件分析共有成分与海拔高度的相关性。不同海拔高度细叶亚菊中挥发油成分差异明显,共有成分5种,分别为樟脑、α-蒎烯、β-蒎烯、桉叶油素、(-)-4-萜品醇。各海拔挥发油中含量最高的化学物质依次为桉叶油素、樟脑、邻-异丙基苯、樟脑、桉叶油素。各海拔相对含量在5%以上的化合物相同的只有桉叶油素。相关性分析结果显示这5种共有成分的含量与海拔并无显著相关性。海拔高度对挥发油中共有成分含量的变化无规律性影响。

Abstract: The aerial parts of Ajania tenuifolia(Jacq.) Tzvel. growing in different regions were collected as raw materials, and the volatile oil was extracted by water distillation. The chemical constituents of volatile oil were analyzed by GC-MS. The correlation between common components and altitudes was studied by SPSS 22.0 statistical software. The volatile oil components of A.tenuifolia were significantly different at different altitudes. There were five common components:camphor, α-pinene, β-pinene, eucalyptol, (-)-terpinen-4-ol. The chemical substances with the highest content of volatile oil at each altitude were eucalyptol, camphor, o-cymene, camphor, and eucalyptus. The same compound with a relative content of more than 5% at each elevation is only eucalyptol. By correlation analysis the content of these five common components was not significantly correlated with altitude. The altitude has no regular influence on the content of essential oils.

Key words: GC-MS, correlation, water distillation method, environmental variables
