The MTT assay performed with a macrophage cell line (RAW 264.7). The BuOH fraction (1, 10, 100, and 200 µg/mL) was dissolved in distilled water resulting in a final concentration of 10 mg/mL, whereas the hydroethanolic extract—(HE, 1, 10, 100, and 200 µg/mL) and the EtOAc fraction (1, 10, 100, and 200 µg/mL) were dissolved in dimethyl sulfoxide (DMSO), resulting in a final concentration of 10 mg/mL. DMSO at two concentrations (1% and 2%) were used to demonstrate its effect on MTT concentration. ** p < 0.01 and * p < 0.05 and tested group compared to the control group (0% DMSO).
