Pelargonium graveolens, commonly known as rose geranium, is an aromatic and medicinal plant belonging to the Geraniacea family. The aim of the present study was to evaluate the in vitro antioxidant and antibacterial activity of Pelargonium graveolens, as well as to determine the total phenolic content of the studied extracts. Four spectrophotometric assays were used for the radical scavenging ability analysis, namely ABTS, DPPH, CUPRAC, and FRAP. The inhibitory activity of the leaves’ extracts was tested against S. aureus, L. monocytogenes, E. coli and Salmonella. The total phenolics ranged from 1.65 to 8.23 mg GAE/g FW. Antibacterial activity, whose zone of inhibition varied from 15 mm to 19 mm depending on the extract quantity, was shown only against L. monocytogenes.
