Conteúdo: 	The objective of this work was to determine the concentration of polyphenols, flavonols, vitamin C and carotenoids in 61 banana accessions from the Musa germplasm collection at Embrapa Cassava and Tropical Fruits, Brazil. Significant differences were detected between accessions for all characteristics analysed by ANOVA. The average polyphenols content was 38. 06 mg/100g, ranging from 12.51 mg/100g in 'Torp' (AAA) to 257.80 mg/100 in 'Teparod' (ABBB). The average flavonols content was 2.10 mg/100g, ranging from 0.85 mg/ 100g in 'Maravilha' (AAAB) to 6.63 mg/100 in 'Temparod'. The average vitamin C content was 21.61 mg/100g ranging from 8.60 mg/100g in the tetraploid 'Bucaneiro' (AAAA) to 76.82 mg/100 in 'Temparod'. The average total carotenoids content was 4.20 g/g, ranging of 0.97 g/g in 'Tropical' (AAAB) to 19.24 g/g in 'Saney' (AAB). 'Modok Gier' (AA) and 'NBA-14' (AA) had 7- and 5- fold higher carotenoids content than the representatives from the Cavendish group ('Nanica', ' Williams' and ' Lacatan', AAA). The genetic variation in the concentrations of these functional components through crossings and selection. cultivars with higher contents of vitamins, vitamin precursors and flavinols have the potential of neutralising free radicals and preventing diseases, including some types of cancer.
