Essential oils (EOs) from Origanum vulgare subsp. vulgare (OVV) and O. vulgare subsp. hirtum (OVH) were evaluated for antioxidant activities (DPPH, ABTS, FRAP, CUPRAC, β-carotene/linoleic acid, phosphomolybdenum and metal chelating), antimicrobial and inhibitory properties against acetylcholinesterase, butrylcholinesterase, tyrosinase, α-amylase and α-glucosidase. Thymol and linalool were identified as major component in OVV and OVH essential oils, respectively. O. vulgare subsp. vulgare exhibited a strong free radical scavenging, reducing power, antimicrobial and acetylcholinesterase, butrylcholinesterase, α-amylase and α-glucosidase inhibitory activity. Interestingly, OVH possess a significant metal chelating and tyrosinase inhibitory activities. The EOs of both species exhibited moderate antibacterial and antifungal activities. The MIC values of the EOs ranged from 85.3 to 426.7. μg/mL. O. vulgare subsp. vulgare showed higher activity against Sarcina lutea with the lowest MIC (85.3. μg/mL), whereas OVH indicated strong activity for Candida albicans with MIC value of 85.3. μg/mL. The data suggest that the Origanum EOs could be used as valuable new natural agents with functional properties for food and pharmacology industries.

Introduction: Mint is used as a herbal tea, in food additives, and as a traditional medicine all around the world. They are popular functional foods and natural remedies. A comprehensive bioactivity evaluation was performed on wild mint essential oil to shed light on its health beneficial effects and therapeutic potential as a very popular herb. Methods: The chemical composition of essential oil of wild mint (Mentha longifolia var. calliantha (Stapf) Briq.) was determined together with its antioxidant and enzyme inhibitory potential linked to Alzheimer's disease, diabetes mellitus, and skin disorders. Six different methods were employed to examine antioxidant ability, including; DPPH, ABTS, CUPRAC, FRAP, metal chelating, and Molybdenum total antioxidant assays. Results: Findings showed that 1,8-cineol (33.5%), linalool (15.1%), menthone (12.9%), and trans-piperitone oxide (12.6%) are the main volatile compounds of the plant. The essential oil exhibited promising antiradical activity (5.8 and 9.1 mmol TEs/g oil in DPPH and ABTS assays, respectively) and reducing power (102 and 337 mmol TEs/g oil in FRAP and CUPRAC assays, respectively). Moreover, remarkable antidiabetic, anticholinesterase, and antityrosinase effects were recorded for the mint oil. Conclusion: Wild mint essential oil has valuable bioactive constituents and great potential for uses in food, pharmaceutical, and cosmeceuticals industries.
