研究了产自秘鲁利马的玛咖（Lepidium meyenii）的精油特征。L. meyenii连续提取戊烷和戊烷提取物进行了GC/MS分析。保留指数和质谱数据被用来确定53个油成分。苯乙腈（85.9%），苯甲醛（3.1%）和3-甲氧基苯乙腈（2.1%）是水蒸气蒸馏油的主要成分。L.测试了Meyenii的植物毒性、杀蓝细菌和抗白蚁活性。与绿色蓝藻羊角月牙藻相比，该油对蓝藻具有选择性毒性，在100 μ g/ml时具有完全的生长抑制。死亡率的台湾地下白蚁，Coptotermes formosanus，是数字，但不显着，较高时，举行的滤纸处理玛咖油。在1%（w/w）下，玛卡油似乎还充当对白蚁的进食威慑。玛咖精油中的几种微量成分，包括3-甲氧基苯乙腈和硫氰酸苄酯，对台湾白蚁有显著的抑制作用。这是首次报道L.梅耶尼。(C)2002爱思唯尔科技有限公司版权所有。
The essential oil profile of maca (Lepidium meyenii) obtained from Lima, Peru, was examined. Steam distillates of the aerial parts of L. meyenii were continuously extracted with pentane and the pentane extracts analyzed by GC/MS. Retention indices and mass spectral data were used to identify 53 oil components. Phenyl acetonitrile (85.9%), benzaldehyde (3.1%), and 3-methoxyphenylacetonitrile (2.1%) were the major components of the steam distilled oil. The oil of L. meyenii was tested for phytotoxic, cyanobactericidal, and antitermite activity. The oil was selectively toxic towards the cyanobacterium Oscillatoria perornata compared to the green alga Selenastrum capricornutum, with complete growth inhibition at 100 mug/ml. Mortality of the Formosan subterranean termite, Coptotermes formosanus, was numerically, but not significantly, higher when held on filter paper treated with maca oil. At 1% (w/w), maca oil also appeared to act as a feeding deterrent to termites. Several minor components of the essential oil of maca including 3-methoxyphenylacetonitrile and benzylthiocyanate were significantly active against the Formosan termite. This is the first report on the essential oil composition of L. meyenii. (C) 2002 Elsevier Science Ltd. All rights reserved.
