RESUMO
Two new guaianolides, 4alpha,10alpha-dihydroxy-1beta(H),5beta(H)-guai-11(13)-en-8alpha,12-olide (2) and 4beta,10beta-dihydroxy-5alpha(H)-1,11(13)-guaidien-8alpha,12-olide (3), from Carpesium macrocephalum were isolated, and their structures were elucidated on the basis of spectroscopic studies.
