摘要：玛咖（Lepidium meyenii Walp．）为十字花科（Cruciferae）独行菜属（Lepidium）1年生或2年生草本植物，原产于秘鲁海拔4000m以上的安第斯山区，这些地区海拔高、土地贫瘠、岩石丛生、风强、气温常处于冰冻状态、气候恶劣，几乎没有其他农作物能生长；因此玛咖的引种栽培，对高寒贫困地区生态环境的改善及经济发展具有积极的促进作用。
The composition and content of sterols in three color types of maca （Lepidium meyenii） cultivated in Yunnan were analyzed by GC-MS. The result showed that all the three types of maca contained β-sitosterol and campesterol. The content of β-sitosterol was higher than that of campesterol. The total sterol content in white, pur- ple and yellow samples were 36. 60, 32. 38, 27. 97 mg·（ 100 g^-1 ）, respectively. Among them, the total sterol content in white sample was the highest. The differences in contents were significant among the three types of sample （P 〈0.01 ）. The composition was consistent with that of sample cultivated in Peru, and the total content of sterol was also very similar.
