Protective effects of baicalein, wogonin, and oroxylin A in Aβ25–35-treated PC12 cells. Measurement of cytotoxicity due to baicalein, wogonin, and oroxylin A in PC12 cells (a). PC12 cells were treated with three compounds for 1 h followed by exposure to 50 μM Aβ25–35 for 24 h, and cell viability was determined by MTT assay, (b) and flow cytometry (c). Statistical analysis results of the percentage of cell viability by flow cytometry (d). Different alphabets indicated significant difference at p < 0.05.
