Effect of the extracts on RAW264.7 macrophages. Cells were incubated for 24 h in the presence of the extracts alone or with LPS. a Effect of different concentrations of the extracts on NO production without LPS stimulation. b Effect of different concentrations of the extracts on NO production in the presence of LPS. c Effect of the extracts on macrophages proliferation in the absence or the presence of LPS. Results represent mean ± SEM of three experiments performed in triplicate. Statistical differences from the control group were determined by ANOVA + Dunnett’s test (*p < 0.05; **p < 0.01; ***p < 0.001 vs. control group; ^#p < 0.05; ^###p < 0.001 vs. LPS group)
