辣木叶正丁醇部位化学成分研究

该文对辣木Moringa oleifera干燥叶的正丁醇萃取部位进行化学成分分离,采用大孔树脂HP-20,凝胶Sephadex LH-20和ODS等色谱技术分离纯化,利用波谱数据(1H,13C-NMR,MS)进行结构鉴定,共分离鉴定17个化合物,分别为咔啉类2个tangutorid E(1),tangutorid F(2);酚苷类3个niazirin(3),benzaldehyde 4-O-α-L-rhamnopyranoside(4),4-O-β-D-glucopyranosidebenzoic acid(5);绿原酸及衍生物4个4-caffeoylquinic acid(6),methyl 4-caffeoylquinate(7),caffeoylquinic acid(8),methyl caffeoylquinate(9);核苷类2个uridine(10),adenosine(11);黄酮类1个quercetin 3-O-β-D-glucopyranoside(12);其他小分子类5个phthalimidineacetic acid(13),3-pyridinecarboxamide(14),3,4-dihydroxy-benzoic acid(15),5-hydroxymethyl-2-furancarboxylic acid(16),5-hydroxymethyl-2-furaldehyde(17)。其中化合物1~2,7,9~10,16~17为首次从该植物中分离得到。
