Chemical composition and antioxidant activity of tronchuda cabbage internal leaves
Ferreres, F.; Sousa, C.; Vrchovska, V.; Valentão, P.; Pereira, J.A.; Seabra, R.M.; Andrade, P.B.A phytochemical study was undertaken on the internal leaves of tronchuda cabbage (Brassica oleracea L. var. costata DC). Seventeen phenolic compounds were characterized and quantified by reversed-phase HPLCDAD-ESI-MSn and HPLC/DAD, respectively: quercetin 3-O-sophoroside-7-O-glucoside, 3-p-coumaroylquinic acid, kaempferol 3-O-sophoroside-7-O-glucoside, kaempferol 3-O-(caffeoyl)-sophoroside-7-O-glucoside, sinapo...

Vrchovska, V.; Sousa, C.; Valentão, P.; Ferreres, F.; Pereira, J.A.; Seabra, R.M.; Andrade, P.B.The ability of the aqueous extract of tronchuda cabbage (Brassica oleracea L. var. costata DC) external leaves to act as a scavenger of DPPH- and reactive oxygen species (superoxide radical, hydroxyl radical and hypochlorous acid) was investigated. A phytochemical study was also undertaken, and thirteen phenolic compounds and five organic acids were identified and quantified. Tronchuda cabbage extracts exhibite...
