Recebido em 17/6/12; aceito em 13/11/12; publicado na web em 20/2/13 CHEMICAL CONSTITUENTS OF Vernonia scorpioides (Lam) Pers. (Asteraceae). The chemical investigation of hexane and ethanol extracts from the aerial parts of Vernonia scorpioides resulted in the isolation and characterization of a new polyacetylene lactone, rel-4-dihydro-4β-hydroxy-5a-octa-2,4,6-triynyl-furan-2-(5H)-one, along with the new ethyl 3,4-dihydroxy-6,8,10-triynyldodecanoate, and seven known compounds: taraxasteryl
