Teucrium species have been among the most commonly used traditional medicinal plants and they are known to have extensive therapeutic applications. The main focus of this study, Teucrium multicaule is also renowned for being an important medicinal and aromatic plant in Turkiye. Volatile profiling of the essential oils was conducted by GC-MS, phytochemical profiling of the ethanol extracts was carried out by LC--HRMS, antioxidant, anticholinesterase, antityrosinase, antiurease, antidiabetic, anticancer, and antimicrobial activities were revealed by different assays. Germacrene D was the most abundant compound in the essential oils from Diyarbakir (TmuD) with 45.4%, and Batman (TmuB) with 54.7%. All extracts were found to be quite rich in phytochemicals by LC--HRMS, and herniarin, caffeic acid, naringenin, luteolin, scutellarein, hispidulin, rhamnocitrin, penduletin, eupatilin, (-)-epigallocatechin gallate, hederagenin, and verbascoside were found to be present in all extracts. T. multicaule roots extract from Diyarbakir (TmuRD) demonstrated the highest radical scavenging, a-amylase inhibitory (59.82 +/- 0.36%), and antibutyrylcholinesterase activity (61.96 +/- 1.72%), whereas T. multicaule aerial parts extract from Batman (TmuHB) exhibited the strongest antityrosinase (66.17 +/- 0.92%), antiurease (67.85 +/- 0.69%), and cytotoxic (54.76 +/- 1.57 mg/mL) activities. TmuRD also showed significant antimicrobial activity against S. epidermidis with 156.2 mg/mL MIC value. As revealed by this first detailed report on T. multicaule, the plant demonstrates various important biological activities attributed to its rich phytochemicals, which also justifies its use in ethnomedicine.(c) 2022 SAAB.
