Physicochemical, Biochemical, and Essential OilDiversity among Peppermint (Mentha × piperita L.“Almira”, Mentha × piperita L. “Granada”,and Mentha × piperita L. “Multimentha”) Cultivars

Three mint varieties (Mentha piperita L. "Almira", Mentha piperita L. "Granada", and Mentha piperita L. "Multimentha") grown in the Medicinal and Aromatic Plants Garden of Van Yznc Yl University were subjected to biochemical, physiological, and essential oil analyses.The present study revealed variations in the examined parameters among the varieties.The values of , flavonol (1.41-1.83dx), anthocyanin (0.06-0.10 dx), total flavonoid content (353.75-288.12mg QE 100 g -1 ), total phenolic content (163.43-185.00mg GAE g -1 ), total antioxidant activity (86.95-154.45mol TE g -1 ), total dry matter (23.0-24.20%),total ash (11.07-13.59%),macronutrient elements (Mg (3.45-5.83g kg -1 ), K (21.34-30.0g kg -1 ), Ca (16.93-22.06g kg -1 )), micronutrients (Fe (593.30-991.12mg kg -1 ), Mn (90.14-110.21mg kg -1 ), Zn (32.39-48.01mg kg -1 ), Cu (9.34-16.75mg kg -1 )), and heavy metal contents (Ni (0.16-4.68 mg kg -1 ), and As (0.16-4.68 mg kg -1 )).The dominant essential oil components were piperitenone oxide (43.38%) and piperitenone (39.4%) for Mentha piperita L. "Almira", linalool (54.19%) and linalyl acetate (20.61%) for Mentha piperita L. "Granada", and menthone (71.50%) and neomenthol (4.90%) for Mentha piperita L. "Multimentha".
