Effect of APH on cell viability of murine macrophages RAW 264.7. Cell viability was assessed 24 h after incubation with increasing concentrations (0.01–100 mg/mL) of APH, showing that only 0.01, 0.05 and 0.1 mg/mL lacked cytotoxicity (a). APH pre-treatment protected Raw 264.7 cells by H₂O₂ damage (b). Data are representative of at least three independent experiments. # p < 0.05; ## p < 0.01 vs. H₂O₂ ** p < 0.01 vs. Ctr.
