Graph showing concentrations of catalase required to reverse antimicrobial effects of white tea sub-fraction combined with 4.8 mM copper (II) sulphate and 4.8 mM vitamin C against S. aureus NCTC 06571. (Cu = copper (II) sulphate, WT = white tea, '+' = combination of agents specified, WTF = white tea fraction (< 1000 Da), Vit C = vitamin C, E300, E600 = added level of enzyme, 300 or 600 μg/mL (f.c.), Sample volumes of 500 μL of Cu+Vit C, WTF+Cu and WTF+Cu+Vit C were used to reduce the detection limit. Bars show SEMs).
