Bioactive compounds in different citrus varieties. Discrimination among cultivars

Cultivars of Clementine mandarin (Arrufatina, Clemenpons, Clemenules, Fino, Hernandina Loretina, Marisol, Crogrande, Oronules and Oroval), Satsume mandarin (Avasa Pri-10, Avasa Pri-19, Ckitsu and Owari), Hybrid mandarin (Fortune, Ortanique and Nova), Navel orange (Fukumoto, Lanelate, Navelate, Navelina, Navel Foyos, Newhall and Powell), Common orange (Salustiana and Valencia Late) and Pigmented orange (Sanguinelli) groups have been analysed for its content in narirutin, hesperidin and total vitamin C. Sweet orange groups presented the higher concentration in flavonoids and total vitamin C. The influence of variety on the content of bioactive constituents and its contribution to taxonomy at the varietal level is studied. (C) 2008 Elsevier Inc. All rights reserved.
