摘要：

New stilbene derivatives designated lehmbachols A-D were isolated from the bark of Salacia lehmbachii, collected in Papua New Guinea. Their structures were established from spectroscopic evidence as 1-[1-methoxy-1-(3-methoxy-4-hydroxyphenyl)methyl]-2-(3,5-dimethoxyphenyl)-3-(3-methoxy-4-hydroxyphenyl)-4,6-dihydroxy-2,3-dihydro-1H-indene and its diastereoisomer, 1-[1-ethoxy-1-(3-methoxy-4-hydroxyphenyl)methyl]-2-(3,5-dimethoxyphenyl)-3-(3-methoxy-4-hydroxyphenyl)-4,6-dihydroxy-2,3-dihydro-1H-indene and 2-(3-methoxy-4-hydroxyphenyl)-5,7-dihydroxy-8-(3,5-dimethoxy-4-hydroxyphenyl)-2,3,9,10-tetrahydro-8H-indeno [1,2-c] furan, respectively.
