Prenylated bisresorcinols from Grevillea floribunda
Seven new bisresorcinol derivatives, together with four known resorcinols, have been isolated from the ethyl acetate extract of the stems of Grevillea floribunda. Five of the new compounds (floribol A–E) were characterized as bisnorstriatol derivatives substituted at C-2 of both resorcinol units with variously modified prenyl (3-methylbut-2-enyl) units. The remaining two new compounds are similarly substituted derivatived of grebustol-B.
