Effects of crude D. viscosa root extract on PC12 cell viability. Mean cell viability (± SD) measured by XTT assay for (A) PC12 cells incubated with concentrations of crude D. viscosa root extract (0–5000 μg/mL) for 14 h or (B) PC12 cells pretreated with concentrations of crude D. viscosa root extract (0–5000 μg/mL) for 2 h followed by incubation for 12 h with H2O2 (400 μM). Two-way ANOVA: crude root extract concentration, p < 0.0001; pretreatment, p < 0.0001; interaction, p < 0.0001. Dunnett’s test: ***, p < 0.0001.
