摘要: The contents and their dynamic arrangements of six antioxidants and total antioxidant capacity in the three mango (Mangifera indica L.) cultivars, 'Tainong No.l' ('Haden' x 'Irwin'), 'Yuexi No.l' (the progeny of 'Carabao') and 'Chunhuang' ('White' x 'Keitt'), were estimated at fruit harvest-maturity (harvesting stage) and edible-ripening stages in South China. The results showed that, both at fruit harvesting and edible-ripening stages, total carotenoid contents and total antioxidant capacity were inthe order: 'Yuexi No.l'>'Tainong No.l'>'Chunhuang'; the ascorbic acid (AA) content was 'Tainong No.l'>'Yuexi No.l' > 'Chunhuang'; total polyphenol content was 'Yuexi No.l'>'Chunhuang'>'Tainong No.l'; reduced glutathione (GSH) content was 'Tainong No.l'>'Chunhuang'>'Yuexi No.l'. At fruit harvesting stage, total flavonoid content was 'Tainong No.l'>'Chunhuang'>'Yuexi No.l' and a-tocopherol content was 'Yuexi No.l'>'Tainong No.l'>'Chunhuang'. And at fruit edible-ripening stage, total flavonoid content was'Yuexi No.l' >'Tainong No.l'>'Chunhuang' and a-tocopherol content was 'Tainong No.l'>'Yuexi No.l' >'Chunhuang'. In addition, total flavonoid content at edible-ripening stage was significantly higher than that at harvesting stage in each cultivar, and 'Yuexi No.l' possessed a conspicuous high level at this stage.
