摘　　要：运用索氏提取法取得火麻仁脂溶性成分,主要考察了不同蒸馏温度对分子蒸馏制备火麻仁精油组分的影响。通过GC-MS分析得出,250℃条件下蒸馏的火麻仁精油分离出136种成分,鉴定出115种挥发性成分,占该火麻仁精油总成分的98.81%,且精油的组分数量随蒸馏温度的增加而增加。其主要物质有:反-1-异丙基-4-甲基环己烷(22.56%)、乙酸(8.43%)、茴香脑(6.50%)、反-3-甲基-6-(1-甲基乙基)环己烯(5.06%)、1-甲基萘(4.36%)、己醛(3.87%)、己酸(2.63%)、萘(2.93%)等物质。This experiment studies the lipid solubility of Cannabis sativa L. by SoxhLet Extraction and the influ- ences on different vaporizing temperatures for molecular distillation to make essential oil of Cannabis sativa L. After analyzing the GC - MS,it can get that the distilled Cannabis sativa L. essential oil under 250 ~C extracts 136 kinds of compound and identifies 115 kinds of volatile components, which represents 98.81% of the total bulk composition of Cannabis sativa L. essential oil and the components number of essential oil is increasing by the increase of tempera- ture. The main substances are： trans - 1 - Isopropyl - 4 - Methylcyclohexane （ 22.56% ） , Acetic acid （ 8.43% ）, Anethol （ 6.50 % ）, Cyclohexene, 3 - methyl - 6 - （ 1 - methylethyl） -, trans - （ 5.06 % ）, Naphthalene, 1 - methyl - （4.36%）, Hexanoic acid（2.63% ）, Naphthalene（2.93% ）.
