AMORIM, Edson Perito et al. Characterization of banana accessions with base on functional compounds. Cienc. Rural [online]. 2011, vol.41, n.4, pp.592-598.  Epub 20-Abr-2011. ISSN 0103-8478.  https://doi.org/10.1590/S0103-84782011005000042.

The objective of this research was to determine the concentration of polyphenols, flavonols, vitamin C and carotenoid and in 61 banana accessions from Musa germplasm collection from Embrapa Cassava and Fruits, Brazil. Was detected significant differences for all characteristic analyzed in ANOVA. The average for polyphenols among the 61 accessions was of 38.06mg 100g-1, with variation of 12.51mg 100g-1 for the triploid 'Torp' to 257.80mg 100g-1 for the tetraploid 'Teparod'. The average for flavonols was of 2.09mg 100g-1, ranging of 0.85mg 100g-1 ('Maravilha' AAAB) to 6.63mg 100g-1 ('Teparod' ABBB). The average for vitamin C was of 21.60mg 100g-1, ranging of 8.60mg 100g-1 (tetraploid 'Bucaneiro') to 76.82mg 100g-1 (tetraploid 'Teparod'). The average of the total carotenoids was of 4.34g g-1, ranging of 1.18g g-1 ('Champa Madras', triploid ABB) to 19.24g g-1 ('Saney', triploid AAB). Diploids Modok Gier and NBA-14 exhibited 4- and 5-fold increased carotenoid content in comparison to the representatives from the Cavendish group ('Nanica', 'Willians' and 'Lacatan'). These results allow ending about the possibility of the obtaining new cultivars with high levels of functional compositions through crossings and selection. Cultivar with this profile has potential of neutralizing free radicals and to prevent diseases.
