Abstract: The objective of this research was to determine the concentration of carotenoids, vitamin C, polyphenols and antioxidant activity of improved varieties of papaya. Four improved varieties from Solo group (L60, L47-05, L47-08 and H54.78), two from Formosa group (L33 and H36.45) and commercial varieties Tainungn.1 and Sunrise Solo were evaluated. Among the Solo group varieties, L47-08 showed high levels of carotenoids and Sunrise Solo the highest content of vitamin C. Among the Formosa group varieties, H36.45 and L33 showed high levels of vitamin C and total polyphenols, as well as higher antioxidant activity. Total polyphenols and vitamin C were significantly correlated with the antioxidant activity of papayas evaluated. [ABSTRACT FROM AUTHOR]
