There are several novel medicines which have been developed from plants and used for treating various diseases after proper pharmacological evaluation. This present study was carried to evaluate the bioactivity viz antibacterial, antioxidant and anticancer potential of ethanolic extract of Aegle marmelos which has been considered to be sacred plant. Ethanol extract of leaves, fruit rind and fruit pulp were used for the bioactivity study. Among the various ethanol extracts, ethanol extract of fruit pulp showed a good antibacterial activity. Fruit rind ethanol extract showed noticeable DPPH scavenging activity with IC 50 value of 159.37μg /ml and anti-proliferating activity with an IC 50 value of 234.28 μg /ml. https://www.biotech-asia.org/vol12_nospl_edn2/evaluation-of-bioactive-potential-of-aegle-marmelos/ Inhibition Concentration50 - IC50; DPPH; Antioxidant; antibacterial; A. marmeloes
