摘要
从黄海棠植物中共分离得到15个化合物,并运用质谱、1H NMR和13C NMR等波谱方法将他们的结构鉴定为9,9'-O-di-(E)-feruloyl-(-)-secoisolariciresinol(1),山奈酚(2),槲皮素(3),金丝桃苷(4),槲皮素-3-O-β-D-吡喃葡萄糖苷(5),山奈酚-3-O-β-D-吡喃半乳糖苷(6),山奈酚-3-O-β-D-吡喃葡萄糖苷(7),原儿茶酸(8),1,7-二羟基-9-氧杂蒽酮(9),对香豆酸(10),对羟基苯甲酸(11),山奈素-3-O-(6”-O-巴豆酰)-β-D-葡萄糖苷(12),1,3,6,7-四羟基-9-氧杂蒽酮(13),没食子酸(14)和β-谷甾醇(15)。其中化合物1、4和6~14为首次从该植物中分离得到。
Fifteen compounds were isolated from Hypericum ascyron L. by repeated column chromatography on silica, Sephadex LH-20 gel, and HPLC. On the basis of MS and NMR spectra, they were identified as 9,9'-O-di- (E)-fenaloyl- (-)-secoisolarieiresinol (1),kaempferol (2),quereetin (3),hyperoslde (4),quercetin-3-O-β-D-glucopyranoside(5), kaempferol-3-O-β-D-galactopyranoside (6), kaempferol-3-O-β-D-glucopyranoside (7), protoeatechuie acid ( 8 ), 1,7-di- hydroxy-xanthone (9), trans-p-eoumarie aeld (10), p-hydroxybenzoie acid ( U ), kaempferol-3-O- ( 6" -O-erotonoyl) -β- D-glueopyranoside (12), 1,3,6,7-tetrahydroxyxanthone ( 13 ), gallic acid ( 14 ) and/3-sitosterol ( 15 ) respectively. A- mong them,compounds 1,4 and 6-14 were isolated from the species for the first time.
