| 摘 要： | 利用水蒸气蒸馏法提取香椿嫩叶挥发油,采用气相色谱-质谱(GC-MS)联用技术对其化学成分进行分离和鉴定,并用峰面积归一化法确定各组分的相对含量。结果共鉴定出68个化合物,占挥发油化学成分相对百分含量的90.23%,其主要成分为长链脂肪烃,包括正二十四烷(7.39%)、正二十烷(6.84%)、正二十七烷(3.82%)、正二十六烷(3.62%)、正二十一烷(3.41%)、正十九烷(2.52%)、正二十二烷(1.85%)、正二十三烷(1.79%)、正十八烷(1.53%)、正二十五烷(1.33%)等。

| Abstract: | Volatile oil fromToonasinensisRoem was extracted via steam distillation. GC-MS was used to analyze the chemical composition of volatile oil and peak area normalization method was used for quantification. Totally 68 compounds were separated and identified, mostly including longchain fatty hydrocarbons such as n-tetracosane（7.39%）,n-eicosane （6.84%）, n-heptacosane（3.82%）, n-hexacosane（3.62%）, n-heneicosane（3.41%）, n-nonadecane（2.52%）, n-docosane（1.85%）, n-tricosane（1.79%）, n-octadecane（1.53%）, n-pentacosane（1.33%）. |
