Antioxidants activity and bioactive compounds in by-products of apple juice


Abstract in English

In this research, the antioxidant capacity(DPPH method), and total phenolic content (assayed by Folin-Ciocalteu method), ,flavonoids, anthocyanins (pH differential method) and ascorbic acids(2,6-dichlorophenol indophenol) in three fruit tissues (peel, pulp and whole fruit), of four apple cultivars commonly in Syria(Red Delicious, Rome Beauty, Starking Delicious, Golden Delicious), were studied.
