Tronchuda cabbage (Brassica oleracea L. var. costata DC) seeds: phenolic compounds and antioxidant potential. In XXIII International Conference on Polyphenols. Winnipeg. p. 483-484http://hdl.handle.net/10198/5373Tronchuda cabbage (Brassica oleracca L. var. "oslalo DC) seeds were studied for their phenolic composition and antioxidant capacity. Thirteen compounds were characterized and quantified by reversed-phase HPLC-OAO-MSIMSESI and HPLC-OAD, respectively: two sinapoylgentiobiose isomers, three sinapoylglucosc isomers, kacmpferol-3- (sinapoyl)sophofOtrioside-7 -gI ucosidc, sinapoyIchol inc; kaempferol-3, 7-diglucoside-4' -(sinapoyl)glucoside, three disinDpoylgentiobiose isomers, 1,2,2' -trisinapoyIgentiobiose and I ,2-disinapoylglucosc. The aqueous extract of tronchuda cabbage seeds WDS investigated for its capacity to act as a scavenger of DPPH radical and reactive oxygen species (superoxide and hydroxyl radicals Dnd hypochlorous acid), exhibiting antioxidant capacity in a concentration dependent manner against all radicalsengconference object
