Abstract(s)
Tronchuda 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 radicals
