摘要
目的研究吉林产玛咖Lepidium meyenii干燥根茎的化学成分。方法采用大孔树脂柱色谱、硅胶柱色谱、ODS反相柱色谱和半制备高效液相色谱等现代技术进行分离纯化,通过理化性质和波谱数据进行结构鉴定。结果从玛咖根茎水提取物中分离得到13个化合物,分别鉴定为N-甲基-3-羟基苯乙酰胺(1)、N-苄基十八碳酰胺(2)、苯乙酰胺(3)、苯甲胺(4)、3-甲氧基苯乙酸(5)、苯乙酸(6)、4-羟基-3-甲氧基-苯甲酸(7)、烟酸(8)、3,4-二羟基甲酸甲酯(9)、腺苷(10)、L-缬氨酸(11)、胡萝卜苷(12)、β-谷甾醇(13)。结论化合物1为首次从天然产物中分离得到,化合物3~6、9为首次从独行菜属植物中分离得到,化合物11、12为首次从玛咖中分离得到。
Objective To study the chemical constituents from the dried rhizome of Lepidium meyenii(Maca) cultivated in Jilin. Methods The chemical constituents were isolated and purified with macroreticular resin, silica gel, ODS column chromatography, preparation HPLC, etc. The structures of the compounds were identified by physicochemical properties and various spectroscopic methods. Results Thirteen compounds were isolated as N-methyl-3-hydroxy-benzeneacetamide(1), N-benzyloctadecanamide(2), benzeneacetamide(3), benzylamine(4), 3-methoxyphenylacetic acid(5), phenylacetic acid(6), 4-hydroxy-3-methoxybenzoic acid(7), nicotinic acid(8), 3, 4-dihydroxy-benzoic acid methyl ester(9), adenosine(10), L-valine(11), daueosterol(12), and β-sitosterol(13). Conclusion Compound 1 is identifled as a new natural compound, and compounds 3—6 and 9—12 are obtained from L. meyenii for the first time.
