菜花中挥发油化学成分气相色谱-质谱联用分析

摘要

目的：分析油菜花挥发油中的化学成分。方法：采用水蒸气蒸馏法提取油菜花挥发油,以气相色谱-质谱联用法挥发油中化学成分的分析。结果：共检测出30种成分,并鉴定出其中21种化合物,其相对含量占挥发油总量的97.40%,主要化合物为正四十烷（38.14%）、正四十四烷（30.24%）、异硫氰酸烯丙酯（10.94%）、异硫氰酸丁烯酯（9.56%）、石竹烯（1.02%）、柠檬烯（1.01%）、硫氰酸烯丙酯（0.75%）等。%Objective： To determine the chemical components in the volatile oil from rape flowers.Methods： The volatile oil in rape flowers was extracted by steam distillation method,and its chemical components were qualified and quantified by gas chromatography-mass spectrometry（GC-MS）.Results： Totally 30 components were found,including 21 identified ones,accounting for 97.40% of total peak area.The major compounds were n-tetracontane（38.14%）,n-tetratetracontane（30.24%）,allyl isothiocyanate（10.94%）,3-butenyl isothiocyanate（9.56%）,β-caryophyllene（1.02%）,limonene（1.01%）,and allyl thiocyanate（0.75%）.
