N2  - 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&#8242;-methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (1); eupomatenoid-16, 7-methoxy-2-(4&#8242;-methoxyphenyl)-3-methyl-5-(E)- propenylbenzofuran (3); eupomatenoid-17, 5-allyl-7-methoxy-2-(4&#8242;- methoxyphenyl)-3-methylbenzofuran (5); eupomatenoid-18, 5-allyl-2- (3&#8242;,4&#8242;-dimethoxyphenyl)-7-methoxy-3-methylbenzofuran (6). Eupobennettin was shown to be (2&#8242;&#945;,3&#8242;&#945;,4&#824;&#946;,5&#8242;&#945;)-5-[3&#8242;,4&#8242;-dimethyl-5&#8242;-(3&#8242;,4&#8242;,5&#8242;-trimethoxyphenyl)tetrahydrofuran-2&#8242;-yl]-2,3-dimethoxyphenol (7). Spectroscopic studies and a biomimetic synthesis proved that bennettinone was 2-(4&#8242;-allyl-2&#8242;-methoxyphenoxy)-1-(3&#8242;,4&#8242;-dimethoxyphenyl)propan-1-one (10).
