MTS assay of concentrations of bacopa extracts (μg/ml) in N9 microglial cell cultures following 24h of treatment. None of the concentrations of the infusion (A), tea (B), or alkaloid (C) fraction resulted in cell death. The double asterisks indicate that cell death occurred at 6 μg/ml of the Bacoside A (D). There were small but significant increases in cell survival compared to media controls in the 12.5 μg/ml tea, the 0.125 and 025 μg/ml alkaloid, and the 1.5 μg/ml Bacoside A suggesting that these concentrations are beneficial for cell survival. Graphs represent mean ± SEM. *p<0.05; ANOVA with Dunnett's post hoc test compared to media control.
