Effect of a) DPPH and b) ABTS on the viability of 3T3 cells. The cells were incubated with DPPH or ABTS for 24 h before being assessed for their viability, compared to those treated with dimethyl sulfoxide (DMSO) or ethanol (EtOH) alone (negative control). Data presented as mean ± standard deviation (n = 3). *Denotes significant difference (p < 0.05) from the control (cells + 0.3% DMSO/EtOH).
