Figure 2

Effect of increasing doses of B. serrata extract A (0.1, 1, 10, and 100 μg dry extract/ml) (a), extract G (2.4, 24, 240, and 2400 μg resin/ml) (b), and pure BAs (low, corresponding to 3.8 ng/ml AKBA, 3 ng/ml KBA, and 8 ng/ml βBA, and high, corresponding to 380 ng/ml AKBA, 300 ng/ml KBA, and 800 ng/ml βBA) (c) on pAECs. Cell viability was measured by MTT assay. Data are reported as of 8 independent replicates. Different letters above the bars indicate significant differences ( ANOVA post hoc Tukey’s test).
