Abstract

The acetone extract of the Brazilian brown alga Dictyota menstrualis (Hoyt) Schnetter, Hörnig & Weber-Peukert was analyzed by HRGC-MS. Eight diterpenoids were identified: pachydictyol A (1), isopachydictyol A (2), dictyol C (3), dictyotadiol (4), dictyoxide (5), 9-hydroxy- and 9-acetoxy-dichotoma-2, 13-diene-16,17-dial (6–7) and 5-hydroxy-1, 6-cycloxenia-2,13-diene-16,17-dial (8). This technique may be an excellent alternative for chemotaxonomic and biogeographic studies.
