Cytotoxicity and cytoprotective effects of Hemerocallis citrina Baroni ethyl acetate fraction (HCEA). (a) BRL-3A cells exposed to various concentrations of HCEA (50–400 μg mL⁻¹) for 24 h. (b) BRL-3A cells pretreated for 24 h with indicated HCEA concentrations before treatment with 500 μM t-BHP. Different lowercase letters indicate significant differences ().
