不同溶剂提取云南丽江栽培玛咖的挥发性成分比较分析

Differences of the main compounds of essential oils extracted by different solvents in Lepidium meyenii Walpers cultivated in Yunnan

摘要:

玛咖是著名的保健植物资源，近年在云南丽江引种成功并大规模栽培。云南丽江栽培玛咖中的挥发性成分采用GC-MS技术进行分析，鉴定出90种挥发性成分。发现石油醚溶浸出挥发性成分的主成分为[(1,1-二甲氧基)甲基]-苯(26.00%)，N-苄基-乙酰胺(23.47%)和邻苯二甲酸己酯(23.49%)；水蒸气蒸馏的挥发性主成分为1-异氰基-2-甲基苯(81.80%)；水蒸气蒸馏水相的挥发性主要成分为苯腈(56.29%)、甲氧基乙醛(10.35%)。而主成分N-苄基-乙酰胺可以作为丽江栽培玛咖中石油醚提取的特征成分，作为质量控制标准之一。

Abstract:

Lepidium meyenii Walpers (MACA), as famous supplement plant source in Cordilleras of South America , have been successfully carried out to be large-scale cultivated in Lijiang of Yunnan province of CHINA.This paper reported.that the differences of the main compounds of essential oils by steam distillation extraction , Petroleum ether leaching , and Ether extraction from Lepidium meyenii Walpers cultivated in Lijiang of Yunnan Province, and Ninety chemical components were analyzed and identified by gas chromatography/mass spectrometry (GC/MS). The Study results showed that the main compounds of essential oils by Petroleum ether leaching is 1,1-dimethylethoxy)methyl]- Benzene (26.00%)，N-(phenylmethyl)- Acetamide(23.47%)，Phthalic acid, hexyl octyl ester(23.49%); and that of steam distillation extraction is 1-isocyano-2-methyl- Benzene(81.80%), that of Ether extraction from steam essential oil of Lepidium meyenii Walpers cultivated in Lijiang is Benzyl nitrile (56.29%) .
