摘要: 为了考察树龄、虫害与巨尾桉叶油成分的相互关系,更好的开发桉树资源,采用水蒸气蒸馏法提取不同树龄(4~6年生)巨尾桉叶油,用GC-MS法对巨尾桉叶油主要化学成分进行鉴定,分析不同树龄和染虫状态的桉叶油成分变化规律。结果表明,随着树龄增加,桉叶油总量逐年增加;生长年限不同,桉叶油中物质的组成及相对含量存在差异。主要成分相对含量变化情况为:桉油醇、乙酸松油酯含量随树龄逐年上升;d-柠檬烯、α-蒎烯相对含量在4到5年达到峰值,5年后开始下降;莰烯、β-蒎烯和α-松油醇逐年下降。被云斑天牛感染的林地,桉油醇、α-蒎烯、β-蒎烯、莰烯呈相对下降趋势,而d-柠檬烯、α-松油醇、乙酸松油酯的含量上升。

Abstract: To investigate the relationship between different tree age/insect infection status and chemical constituents of essential oil from the leaves of Eucalyptus grandis×E.urophylla, aiming to empolder it efficiently. Eucalyptus essential oil was extracted by steam distilling (SD) and analyzed by GC-MS method.The results showed that along with the increasing of tree age,the amount of Eucalyptus oil increased year by year.However,the composition and relative contents of essential oil varied yearly.The changes of relative content of main component was:Cineole and terpinyl acetate increased with time increments;Camphene,β-pinene and α-terpineol decreased annually;d-Limonene and α-pinene reached a peak in 4 to 5 years,and then began to decline.While infected by Batocera horsfieldi (HoPe),the amount of cineole,α-pinene, β-pinene and camphene was relatively decreased,but the contents of d-limonene,α-terpineol and terpinyl increased.

Key words: Eucalyptus grandis×, E.urophylla, essential oil, age, Batocera horsfieldi (HoPe)
