The objectives of this study were to define the phenolic profile, antioxidant, antimicrobial and anti-inflammatory properties of extracts from Betonica officinalis and Salvia officinalis herbs used in traditional medicine. The results indicated that the extract inhibits scavenges stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) cation radicals. In the present study, Salvia officinalis was potent antibacterial agent against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. The extracts inhibited cyclooxygenase (COX-1) and denaturation of protein, which suggests these species might be a potential source of plant-derived anti-inflammatory substances. Our study, for the first time, revealed the antimicrobial and anti-inflammatory activity of the Betonica officinalis herb. The results of this study could be helpful to develop medicinal preparations and uses of this species as an antimicrobial, anti-inflammatory and wound healing agent.
