Intracellular reactive oxygen species (ROS) scavenging activity of B. formosana callus extract. A Relative DCFH-DA fluorescence in Hs68 fibroblast cells. B Relative DCFH-DA fluorescence in HaCaT keratinocytes. 0.03% tocopherol was used as the positive control and presented as TOC. Data are presented as means ± SD of triplicate experiments. *p < 0.05, **p < 0.01, and ***p < 0.001 compare with control. #p < 0.05, ##p < 0.01, and ###p < 0.001 compare with relative cell viability of the same group
