<P>Thunbergols A (4) and B (5), tetraprenyltoluquinols, along with three known compounds (1—3) have been isolated from the brown alga <I>Sargassum thunbergii</I>. The structures of these two new compounds were determined to be 9-(3,4-dihydro-2,8-dimethyl-6-hydroxy-2<I>H</I>-1-benzopyran-2-yl)-6-methyl-2-(4-methyl-3-pentenyl)-(2<I>E</I>,6<I>E</I>)-nonadienoic acid (4) and 10-(2,3-dihydro-5-hydroxy-7-methyl-1-benzofuran-2-yl)-10-hydroxy-6-methyl-2-(4-methyl-3-pentenyl)-(2<I>E</I>,6<I>E</I>)-undecadienoic acid (5), respectively, by combined spectroscopic methods. Both of them exhibited significant scavenging activities on radical and potently inhibited generation of ONOO<SUP>−</SUP> from morpholinosydnonimine (SIN-1).</P>
