Although the total phenolic content of the ethyl acetate extract of R. officinalis (41.8 mg GAE/g dry weight) is higher than that of L. angustifolia (12.7 mg GAE/g dry weight), the corresponding radical scavenging activity of R. officinalis (19.3%) is higher than those of other plants. The total phenolic content of the methanolic extract of R. officinalis (34.8 mg GAE/g dry weight) is higher than those of other plant species. At the same time, its corresponding antioxidant activity is higher (21.8%). It was established that there was positive linear correlation between radical scavenging activity and total phenolic contents.en10.14233/ajchem.2013.13482info:eu-repo/semantics/openAccessHerbsLabiataeAntioxidant activityDPPHPhenolic contentArticle25630113013WOS:000317245900017Q4
