【摘要】 从蛇菰科植物蛇菰 (BalanophoraharlandiiHook .f.)花序的乙醇提取物中分离到 11个化合物。分别鉴定为 :桐甾醇 (1)、桐甾醇 - 3-O - (6′ -O -棕榈酰基 ) - β -D -葡萄吡喃糖甙 (2 )、 (- ) -lariciresinol (3)、 (- ) -松脂醇 [(- ) -pinoresinol](4 )、β -香树脂醇 (5)、乙酸蛇麻脂醇酯 (6 )、棕榈酸 (7)、 1-O -咖啡酰基 - β -D -葡萄吡喃糖 (8)、 1-O -咖啡酰基 - (6 -O -没食子酰基 ) - β -D -葡萄吡喃糖 (9)、 1-O -咖啡酰基 - (4 -O-没食子酰基 ) - β -D -葡萄吡喃糖 (10 )以及没食子酸 (11)。应用 2DNMR技术对化合物3,4 ,8,9和 10的氢和碳的核磁共振信号进行了全归属。化合物 9和 10尚未见从植物中分离到的报道 ,化合物 1,2 ,8和 11系首次从该科植物中分离得到。更多还原

【Abstract】 Eleven compounds were isolated from the inflorescence of Balanophora harlandii Hook.f. On the basis of spectroscopic data, their structures were established as clerosterol (1)、clerosterol-3-O-(6-O-palmitoyl)-β-D-glucopyranoside(2), (-)-lariciresinol(3), (-)-pinoresinol (4),β-amyrin(5), lupeol acetate(6), palmitic acid(7), 1-O-caffeoyl-β-D-glucopyranose(8), 1-O-caffeoyl-(6-O-galloyl)-glucopyranose(9), 1-O-caffeoyl-(4-O-galloyl)-β-D-glucopyranose(10)and gallic acid(11)respectively. Among them, compounds 9 and 10 are first isolated from plants, and 1, 2, 8 and 11 are first obtained in the family Balanophoraceae. The chemical shifts of 1H and 13 C NMR spectra of 3, 4, 8, 9 and 10 were also assigned completely.更多还原
