RESUMO
Three new oxidative metabolites of lycopenes, (erythro)-lycopene-5,6-diol, (threo)-lycopene-5,6-diol, and 1,16-dehydro-2,6-cyclolycopene-5-ol B, and four new oxidative metabolites of γ-carotenes, 2',6'-cyclo-γ-carotene-1',5'-diol A, 2',6'-cyclo-γ-carotene-1',5'-diol B, (erythro)-γ-carotene-5,6-diol, and (threo)-γ-carotene-5,6-diol, were isolated as minor components from the aril of gac, Momordica cochinchinensis. These structures were determined on the basis of spectroscopic data, and some of them were compared to the structures of synthetic samples. Furthermore, the oxidative metabolic conversion pathways of lycopene and γ-carotene were discussed.
