The emphasis of this review is on linear furano-and pyrroloterpenoids, together with their relevant biological activities, source organisms and country of origin. First total syntheses that lead to the revision of structures or stereochemistries have been included, and 206 references are cited.

O fracionamento biodirecionado do extrato etanólico das raízes da espécie Ozoroa insignis, colhida na Guiné-Bissau, conduziu ao isolamento de uma biblioteca de 41 compostos alquil-e alquenil-fenólicos, cujas estruturas foram elucidadas por RMN 1 H e 13 C, e CGEM. A localização das insaturações nas cadeias laterais dos alquenil-fenóis foi determinada por CGEM dos respectivos derivados metiltiolados. Bioassay-guided fractionation of the ethanolic root extract of Ozoroa insignis, collected in Guinea-Bissau, led to the isolation of a 41-member library of alkyl and alkenylphenols, whose structures were determined by 1 H and 13 C NMR, and GCMS. Determination of double-bond positions in the side chains of alkenylphenols were established by methylthiolation-GCMS.
