摘 要 ：为了研究领春木(Euptelea pleiospermum Hook. f. et Thoms)的化学成分,利用各种柱色谱及高压液相色谱等方法进行分离和纯化,根据理化性质和光谱数据分析鉴定了9个化合物。他们分别为:白桦脂酸 (1);齐墩果酸 (2);N-反式对羟基肉桂酰基-对羟基苯乙胺 (3);N-反式阿魏酰酪胺 (4);N-顺式阿魏酰酪胺 (5);丁香脂素 (6);N-顺式阿魏酰-3-甲氧基酪胺 (7);N-反式阿魏酰-3-甲氧基酪胺 (8);3-羟基-30-去甲基-20-酮基-28-羽扇豆酸 (9)。所有化合物均为首次从领春木中分离得到。
Abstract:To study chemical constituents of Euptelea pleiospermum Hook. f. et Thoms, nine compounds were isolated with column chromatography and HPLC. On the basis of physicochemical properties and spectral data, their structures were identified as: platanolic acid (1), oleanolic acid (2), N-p-trans-coumaroyl tyramine (3), N-trans-feruloyltyramine (4), N-cis-feruloyltyramine (5), syringaresinol (6), N-cis-feruloyl-3-O-methyldopamin (7), N-trans-feruloyl-3-O-methyldopamin (8), 3-hydroxy-30-nor-20-oxo-28-lupanoic acid (9). All compounds were isolated from this plant for the first time.
