文摘

The lipophilic extractives of the unripe peel of ten banana cultivars belonging to the Musa acuminata and Musa balbisiana species (namely ¡®Giant Cavendish¡¯, ¡®Chinese Cavendish¡¯, ¡®Grand Nain¡¯, ¡®Gruesa¡¯, ¡®Williams¡¯, ¡®Ricasa¡¯, ¡®Eilon¡¯, ¡®Zelig¡¯, ¡®Dwarf Red¡¯ and ¡®Silver¡¯) were studied by gas chromatography-mass spectrometry. The extractives content were in the range of 2-3 % with substantially higher values for ¡®Silver¡¯ and ¡®Dwarf Red¡¯ (5.7 and 10.7 % respectively). Sterols and fatty acids were the major families of compounds identified, with respectively 55.1-87.5 % and 10.6-43.2 % of total of lipophilic components. Cycloeucalenone was the main component identified in ¡®Williams¡¯ and ¡®Dwarf Red¡¯, with abundances ranging from 806 to 9453 mg Kg^?1 of dry unripe peels, respectively. The identification of high contents of valuable compounds, can open new strategies for the valorization of the studied banana residues and particularly of those from ¡®Dwarf Red¡¯ followed by ¡®Silver¡¯ and ¡®Ricasa¡¯, as potential sources of high-value phytochemicals.
