Chemotaxonomical research in higher plants (XVI) carotenoid pigments in the fruits of some local varieties of Cucurbita
Keywords:Cucurbita maxima, Carotenoids, Local varieties
The pigments of seven local Cucurbita varieties were determined. In the fruits only carotenoids with alfa- and beta-iononic structure were identified: hydrocarbon carotenoids (alfa- and beta-carotene), xanthophylls (cryptoxanthin, aloxanthin, mutatoxanthin, auroxanthin, violaxanthin, neoxanthin). Quantitatively, the main carotenoid pigments are beta-caroten and zeaxanthin, flavoxanthin and violaxanthin. There are differences among the varieties of C. maxima, both quantitatively and qualitatively, due to genetic and/or environmental influences.
