Biochemical Diversity and Nutraceutical Potential of Medicinal Plant-Based Herbal Teas from Southwestern Turkiye.

ABSTRACT: Medicinal and aromatic plants contain valuable natural compounds widely used in health, food, and cosmetics. This study compares the antioxidant capacities and phenolic compositions of tea and ethanol extracts from eight species naturally growing in Fethiye, Muğla, Türkiye. Antioxidant activity was assessed using the β-carotene bleaching method, 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS⁺), cupric reducing antioxidant capacity (CUPRAC), and metal chelating activity. Herbal teas generally showed stronger antioxidant activity than ethanol extracts. Rosemary tea had the highest activity (2.90 µg/mL), followed by lavender (11.30 µg/mL). In metal chelating, rosemary tea exhibited a half-maximal inhibitory concentration (IC
