乌榄果实挥发性化学成分的GC-MS分析

采用水蒸气蒸馏法对乌榄果实挥发油进行提取，运用毛细管气相色谱- 质谱联用法结合计算机检索对乌榄果实挥发油进行成分分析和鉴定，经毛细管色谱分离出43 个峰，共确认了其中41 种化合物，所鉴定化合物的含量占全油的97.8%。用气相色谱面积归一化法测定了各组分的相对百分含量。其化学成分主要为：1- 甲基-2-(1- 甲乙基) 苯、D- 柠檬烯、α- 侧柏烯、α- 蒎烯、己酸、己醛、石竹烯、氧化石竹烯、1- 戊醇、1- 己醇、β - 水芹烯、古巴烯、α- 蛇麻烯、2- 戊基- 呋喃、壬醛、杜松烯、(-)- 斯帕苏烯醇和[1R-1 α,4a β,8a α]- 十氢-1，4a- 二甲基-7-(1- 甲基乙缩醛基)-1- 萘醇，以上十六种化合物占其挥发油总量的85.88%。

GC-MS Analysis of Chemical Constituents of Volatile Oil from Fruits of Canarium pimela Leenh.

Essential oil from fruits of Canarium pimela Leenh. was extracted by steam distillation and analyzed by capillary GC-MS method combined with computer retrieval. More than 43 peaks were isolated and 41 compounds were identified, which accounted for 97.8% of the total essential oil. The relative percentages of these compounds identified were determined by GC area normalization method. The main chemical components were 1-methyl-2-(1-methylethyl)-benzene, D-limonene, α- Phellandrene, α-pinene, hexanoic acid, hexanal, caryophyllene, caryophyllene oxide, 1-pentanol, 1-hexanol, β-phellandrene, copaene, α-humulene, 2-pentyl-furan, nonanal, cadinene, (-)-spathulenol and decahydro-1,4a-dimethyl-7-(1-methylethylidene)- [1R-(1α,4aβ,8aα)]-naphthalenol, which accounted for 85.88% of the total essential oil.
