摘　　要：目的对吉林产玛咖(Lepidium meyenii Walp.)地下根茎挥发油的化学成分进行检测。方法采用水蒸气蒸馏法提取挥发油,应用气相色谱-质谱联用技术鉴定其化学成分,面积归一化法测定其相对含量。结果共分离出70个峰,鉴定了其中27个化学成分。已鉴定成分占挥发油总量的99.818%。结论挥发油中的主要成分为苯乙腈、3-甲氧基苯甲醛和正十六烷酸,为玛咖的进一步开发提供理论基础。Objective To analyze the chemical components of volatile oil extracted from the root of Maca （Lepidium meyenii Walp.） grown in Jilin Province of China. Methods Volatile oil was extracted by water-steam distillation. The components were quantitatively determined by the normalization method and identified by GC-MS. Results 70 chromatographic peaks were detected. 27 compounds of them have been identified through the computer standard spectra that accounts for 99.818% of the total amount of volatile oil. Conclusion The main components in the volatile oil are Benzyl nitrile, （3-Met hoxyphenyl）acetonitrile and n-Hexadecanoic acid. This study provides theoretical foundation for the further applications of Maca （Lepidium meyenii Walp.） grown in Jilin Province of China,
