Abstract

The antibacterial, antioxidant activity, and anticancer of the extract from Vernonia Amygdalina Del leaves, was assessed towards 6 selected bacteria, in the DPPH test, as well as on hepatic (HepG2), blood (K562) cancer cell lines. The DPPH assay revealed that the highest DPPH radical scavenging activity with the warm ethanol extract (IC50 = 259,03 ± 5,42 μg/mL). And the ethyl acetate extract showed a high antibacterial effect expressed as minimum inhibitory concentration (MIC = 100 mg/mL) against Gram-positive bacteria. At the concentration of 250 mg/mL, this extract also demonstrated its ability to resist blood cancer cells K562 (with a survival rate of 25%) and liver cancer cells HepG2 (with a survival rate of 0%).
