木里柠檬叶精油化学成份的研究

A Study on the Chemical Components of the Essential Oil from Leaves of the Citrus Limon (L.) Burm.f.

用毛细管气相色谱-质谱-计算机数据联用技术、标准品叠加法和毛细管保留指数定性法分析了木里柠檬(Citrus Liilion(L.)Burm.f.)的叶精油化学成分。从水蒸汽蒸馏叶精油被分离的110多个色谱峰中鉴定了41种化合物,并测定了其相对含量。其主要成分是香叶醛(21.3058％)、橙花醛(13.9580)、d-柠檬烯(9.8359)、β-水芹烯(9.3297)、橙花醇(4.4657)、乙酸橙花酯(2.8162)、香茅醛(2.6338)、乙酸芳樟酯(2.2179)、α-水芹烯(2.0390)、香芹酮(2.0213)、6-甲基-5-庚烯-2-酮(1.7250)和乙酸香叶酯(1.6586)。被鉴定的成份占总成份的96.6652％

The chemical components of the essential oil from leaves of Citrus Limon Burro. f.has been studied by means of GC-MS-DS technique, the retention indices of capillarly gas chromatography and authentic sample superimpositiom. Forty-one constituents has been identified from one hundred and eleven seperated peaks of steam-distilled leaf oil The main constituents is Geranial (21.3058%), Neral (13.9580％), d-Limonene (9.83590％), β-Phellandrene (9.3297%), Nerol (4.4657%), Neryl Acetate (2.8162％), Citronellal (2.6338%), Linalyl Acetate (2.2197) etc. The identified components makes up 96.6652% of the total oil.
