摘要: 玛咖是近年来引种国内的秘鲁特产植物,对云南栽培的玛咖块根石油醚提取物中脂肪酸和不皂化物种类与含量进行了分析,皂化物中共鉴定出20种已知成份和3种未知成份,其中亚油酸含量最高,占总皂化物的38.09%,不皂化物中共鉴定出23种已知成份和4种未知成份,其中γ谷甾醇含量最高,占总不皂化物的39.28%,根据质谱特征离子碎片分析,初步判定提取物中未知成分为玛咖烯和玛咖酰胺类物质。

Abstract: Maca (Lepidium meyenii Walp.),which is a special local plant in Peru,was introduced to China in recent years.The fatty acids and unsaponifiable matters of petroleum ether extract in Yunnan maca roots were analyzed.In the saponifiable fraction,20 known and 3 unknown components were identified;in which linoleic acid content is the highest,accounting for 38.09%.In the unsaponifiable fraction,23 known and 4 unknown constituents were identified;in which γsitosterol content is the highest,accounting for 39.28%.According to the characteristic fragment ions based on mass spectrometry analysis,unknown constituents in the extract were deduced for macaenes and macamides.

Key words: Lepidium meyenii., fatty acids, unsaponifiable matters
