云南产玛卡乙酸乙酯部位化学成分研究

On Chemical Constituents of Ethyl Acetate Fraction fromLepidium Meyenii

研究云南产黄色玛卡根部乙酸乙酯部位的化学成分.采用硅胶柱色谱、薄层色谱、制备高效液相等方法进行分离纯化,通过理化常数和波谱数据鉴定化合物结构.从玛卡根部乙酸乙酯部位分离鉴定了8个化合物,分别为1N-苄基十六碳酰胺,2β-谷甾醇,3N-苄基十八碳酰胺,4松脂素,5苯乙酰胺,6β-胡萝卜苷,7尿嘧啶,8松脂素-4′-O-β-D-葡萄糖苷,其中化合物8首次从玛卡中获得.

Researches have been done to study the chemical constituents of ethyl acetate fraction of yellow Maca（Lepidium meyenii）.Isolation and purification have been carried out on column chromatography of silica gel,TLC and preparative HPLC.The structures of these compounds have been elucidated by physico-chemical properties and spectral date.It is concluded that eight compounds are isolated fromLepidium meyenii,which are identified as ①N-benzyl-palmitamide,②β-sitosterol,③N-benzyloctadecanamide,④Pinoresinol,⑤Benzeneacetamide,⑥β-daucosterol,⑦Uracil,⑧Pionresinol-4′-O-glucoside.The result is that one compound8 is isolated fromLepidium meyenii for the first time.
