The aromatic herb Melissa officinalisL. can be used as an easily accessible source of natural antioxidants andas a possible food supplement and as a phytochemical. Radical scavenging, antibacterial, and antiproliferative activities of pe-troleum ether, chloroform, ethyl acetate, n-butanol, and water extracts of M. officinalis L. extracts were investigated. The re-sults of antioxidative activity, obtained by electron spin resonance spectroscopy, confirmed that investigated extracts sup-pressed the formation of 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl, and lipid peroxyl radicals in all investigated systemsin a dose-dependent manner. The maximum DPPH and hydroxyl radical scavenging activities (SADPPH. SAOH . 100%)were achieved in the presence of n-butanol extract at concentrations of 0.4 mg/mL and 0.5 mg/mL, respectively. The highestlipid peroxyl scavenging activity (93.20%) was observed at a higher concentration (5 mg/mL) ofn-butanol extract in the lipidperoxidation system. The most effective antibacterial activities were expressed by petroleum ether and ethyl acetate extractson Sarcina lutea. Chloroform extract showed the strongest antiproliferative effect with 50% inhibitory concentration valuesof 0.09 mg/mL and 0.10 mg/mL for HeLa and MCF-7 cell lines, respectively. The present study demonstrated the high phe-nolic content and radical scavenging, antibacterial, and antiproliferative activities of extracts of M. officinalisL. originatingfrom Serbia.
