All extracts displayed antibacterial activity against test microorganisms except for Escherichia coli. The methanol (TBM) extract with an IC50 value of 0.180 mg/mL exhibited good antioxidant activity against DPPH radical while all extracts showed significant anti-inflammatory activity against lipoxygenase enzyme. The ethyl acetate (TBEA) extract presented moderate activity against alpha-glucosidase enzyme with an IC50 of 0.808 mg/mL. The highest total phenol content with 91.050 mg GAE/g extract was found in TBM. It is the first study on the isolation of secondary metabolites as well as 5-lipoxygenase and alpha-glucosidase inhibitory activity of T. balsamita growing in Turkey.enginfo:eu-repo/semantics/closedAccessTanacetum balsamitasesquiterpene lactonesflavonoidscoumarinsteroidbiological activitySESQUITERPENE LACTONESANTIOXIDANT ACTIVITYANTIMICROBIAL ACTIVITYCHEMICAL-COMPOSITIONESSENTIAL OILIN-VITROFLAVONOIDSCONSTITUENTSAGENTSETHERarticleWOS:00072016330000110.1080/14786419.2021.2005594347919651478-6427
