The genus Satureja (Lamiaceae) includes many aromatic species with known antimicrobial, antioxidant, anti-inflammatory,
and anticancer properties. Satureja hasturkii H.Duman & Dirmenci is a newly described species from Türkiye (2023), and its
biologicalpotentialhasnotbeenexploredyet.Inthisstudy,dichloromethane(DCM),ethylacetate(EtOAc),andethanol(EtOH)
extracts were assessed for their enzyme inhibitory activity against acetylcholinesterase (AChE), butyrylcholinesterase (BChE),
elastase,collagenase,tyrosinase(TYR),andxanthineoxidase(XO),alongwiththeirantioxidantactivitiesusingDPPH,nitricoxide
(NO), metal-chelation,ferric-reducingantioxidantpower (FRAP),and cupric-reducingantioxidantcapacity (CUPRAC) assays.
The extracts showed low to moderate inhibition levels at 2 mg/mL (stock concentration). The EtOAc extract showed the most
effectiveelastase(16.70± 2.08%)andcollagenase(13.96± 3.70%)inhibition.XOinhibitionwashighestwithEtOH(34.34± 0.60%),
