| 摘 要： | 为了分析不同年限巨尾桉叶挥发油的化学成分及生长年限对化学成分组成的影响,采用水蒸气蒸馏法,分别提取2006～2010年种植的巨尾桉叶片中的挥发性成分,并用气相色谱质谱联用技术分析鉴定其化学成分。结果表明:不同生长年限的巨尾桉叶片挥发油产量在0.55%～1.35%之间,随生长年限的增加而升高。利用GC-MS共鉴定出63个化合物,占总挥发油的93.00%～97.07%。其中相对含量较高的物质为:1,8-桉叶油素(55.72%～63.47%)、α-松油醇(9.78%～14.15%)、乙酸松油酯(4.96%～7.06%)、α-蒎烯(0.99%～4.31%)、龙脑(2.40%～4.89%)。由于生长年限的不同,挥发油中物质的组成及相对含量均存在差异。

| Abstract: | In order to analyze chemical composition of volatile leaf oil of E.grandis×E.urophylla with different years old in 2006-2010and explore the influence of growth years.Steam distillation was used to obtain the essential oil and analyzed by gas chromatography-mass spectrometry ( GC-MS ) .The essential oils in yields varied from 0.55%to 1.35% , with the growth years longer , the oil yeild of E.grandis×E.urophyllaincreased.63compounds were identified by GC-MS , representing 93.00%to 97.07%of the total oil composition.The main components were 1 , 8-cineole ( 55.72%-63.47% ), followed byα-terpineol ( 9.78%-14.15% ), α-Terpinyl acetate ( 4.96%-7.06% ), α-pinene ( 0.99%-4.31% ) and Fenchol ( 2.40%-4.89% ) .The composition and relative contents of volatile components varied a lot in different years. |
