Carob Pods (Ceratonia siliqua L.) as a Source of Polyphenolic Antioxidants
نویسندگان
چکیده
The possibility of utilising chopped and deseeded carob pods (kibbles) as a source of polyphenolic antioxidants was examined by performing extractions with various solvent systems, in order to evaluate and optimize the conditions for the recovery of polyphenols. Maximum quantities of polyphenolic components were found in 80 % acetone extracts, as evaluated by measuring total polyphenol and total flavanol content. By contrast, ethyl acetate was inefficient in extracting polyphenols. The assessment of the antioxidant potency of carob pod extracts employing two characteristic in vitro models showed that carobs contain polyphenols with appreciable antiradical and reducing properties. The values obtained were compared to the data on red wines and pure polyphenolic antioxidants.
