Effects of DMF, TMF, PMF, and QC (positive control) on cell viability in HDFs. HDFs were plated in 96-well plates at a density of 1 × 10⁴ cells/well and starved with serum-free media for 24 h. Next, the cells were treated with specific concentrations of the sample for 24 h. Cell viability was determined using the Ez-Cytox kit. The data are presented as mean ± SEM (n = 3). # p < 0.05 compared to non-treated group. Abbreviations: DMF, 5,7-dimethoxyflavone; TMF, 5,7,4′-trimethoxyflavone; PMF, 3,5,7,3′,4′-pentamethoxyflavone; and QC, Quercetin.
