Total flavonoid extract from saffron petals (TFESP) restrains reactive oxygen species (ROS). Fluorescence of BRL-3A cells: (a) observed under fluorescence microscope (100x magnification); (b) detected by flow cytometry; (c) quantified. Statistical significance: ^#, ^##, ^###, and ^####, contrasted to the control group; , , , and , contrasted to the t-BHP-treated group.
