The physicochemical characteristics, fatty acid, tocopherol, and carotenoid composition of a crude oil extracted from papaya (Carica papaya L.) seeds, formosa variety, were investigated. The oil yield from the seeds was 29.16%. The data obtained for the analytical indexes were in agreement with those of other edible oils. The oil obtained had high oxidation resistance (77.97 hours). The major fatty acids in total lipid were oleic (71.30%), palmitic (16.16%), linoleic (6.06%), and stearic (4.73%) acid. The &#945; and &#948;-tocopherol were the predominant tocopherols with 51.85 and 18.89 mg.kg-1, respectivelly. The &#946;-cryptoxanthin (4.29 mg.kg-1) and &#946;-carotene (2.76 mg.kg-1) were the carotenoids quantified, and the content of total phenolic compounds was 957.60 mg.kg-1. Therefore, the potential utilization of the papaya seeds for oil production seems favorable. However, toxicological studies need to be carried out before the oil is appropriate for food applications. As características físico-químicas e as composições de ácidos graxos, tocoferóis e carotenoides do óleo bruto extraído de sementes de mamão (Carica papaya L.), variedade formosa, foram investigadas. O rendimento em óleo das sementes foi de 29,16%. Os dados obtidos para os índices analíticos comparam-se bem com os de outros óleos comestíveis. O óleo apresentou elevada resistência à oxidação (77,97 horas). Os principais ácidos graxos quantificados foram o oleico (71,30%), seguido pelo palmítico (16,16%), linoleico (6,06%) e esteárico (4,73%). O &#945; e &#916;-tocoferol foram os tocoferóis predominantes com 51,85 e18,9 mg.kg-1, respectivamente. A &#946;-criptoxantina (4,29 mg.kg-1) e o &#946;-caroteno (2,76 mg.kg-1) foram os carotenóides quantificados e o conteúdo de compostos fenólicos totais foi de 957,60 mg.kg-1. Assim, a potencial utilização das sementes de mamão para a produção de óleo parece ser favorável. Entretanto, estudos toxicológicos são ainda necessários antes de o óleo ser indicado para utilização em alimentos
