Abstract: Eleven compouds 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[(-)-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.

摘要： 从蛇菰科植物蛇菰（Balanophora harlandii Hook.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2D NMR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。
