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.
