dc.descriptionSquashes and pumpkins are important dietary sources of carotenoids worldwide. The carotenoid composition has been determined, but reported data have been highly variable, both qualitatively and quantitatively. In the present work, the carotenoid composition of squashes and pumpkins currently marketed in Campinas, Brazil, were determined by HPLC-DAD, complemented by HPLC-MS for identification. Cucurbita moschata 'Menina Brasileira' and C. moschata 'Goianinha' had similar profiles, with beta-carotene and alpha-carotene as the major carotenoids. The hybrid 'Tetsukabuto' resembled the Cucurbita pepo 'Mogango', lutein and beta-carotene being the principal carotenoids. Cucurbita maxima 'Exposição' had a different profile, with the predominance of violaxanthin, followed by beta-carotene and lutein. Combining data from the current study with those in the literature, profiles for the Cucurbita species could be observed. The principal carotenoids in C. moschata were beta-carotene and alpha-carotene, whlereas lutein and beta-carotene dominate in C. maxima and C. pepo. It appears that hydroxylation is a control point in carotenoid biosynthesis.
