摘要：

The structures of new extractives from the tubers and aerial parts of Eupomatia bennettii F. Muell. have been assigned as follows: eupomatenoid-15, 2-(4'-methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (1); eupomatenoid-16, 7-methoxy-2-(4'-methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (3); eupomatenoid-17, 5-allyl-7-methoxy-2-(4'-methoxyphenyl)-3-methylbenzofuran (5); eupomatenoid-18, 5-allyl-2-(3',4'-dimethoxyphenyl)-7-methoxy-3-methylbenzofuran (6). Eupobennettin was shown to be (2'-alpha,3'-alpha,4'-beta,5'-alpha)-5-[3',4'-dimethyl-5'-(3'',4'',5''-trimethoxyphenyl)tetrahydrofuran-2'-yl]-2,3-dimethoxyphenol (7). Spectroscopic studies and a biomimetic synthesis proved that bennettinone was 2-(4'-allyl-2'-methoxyphenoxy)-1-(3'',4''-dimethoxyphenyl)propan-1-one (10).
