Various flavonoid derivatives and their efficacy in antioxidant/radical quenching assays. The C2=C3 double bond in conjunction with 3-OH in flavonol (entry 5d), that confer significant antioxidant properties, are highlighted in red with dotted outline. In vitro assay outcomes in which these chemical series are described are given below where these have been reported in the primary papers (see text for details). BCLA β-carotene/linoleic acid assay, FRAP (AAE) ferric reducing/antioxidant power assay, DPPH 2,2-diphenyl-1-picrylhydrazyl, ABTS 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid, SUP superoxide
