    Abstract:
    The antioxidant, nitric oxide (NO) scavenging and malondialdehyde (MDA) scavenging activities of different Zataria multiflora (ZM) chemotype essential oils (EOs) were investigated. The main components are: ZM1 (carvacrol, p-cymene), ZM2 (carvacrol, p-cymene), ZM3 (carvacrol, p-cymene), ZM4 (linalool), ZM5 (carvacrol, p-cymene, thymol), ZM6 (thymol, carvacrol, p-cymene, γ-terpienene), ZM7 (thymol, p-cymene, γ-terpienene) and ZM8 (carvacrol, linalool, p-cymene, thymol). The antioxidant capacities were estimated to be 863 ± 55, 619 ± 27, 876 ± 32, 38 ± 9, 649 ± 50, 595 ± 40, 696 ± 41 and 618 ± 9 µg ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. The NO scavenging values were estimated to be 54 ± 1.2, 50 ± 1.4, 63 ± 1, 0.60 ± 0.1, 53 ± 0.7, 53 ± 1.5, 38 ± 1.1 and 46.5 ± 3 µg ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. The MDA scavenging values were estimated to be 19 ± 1, 9 ± 1, 24 ± 1, 1.6 ± 0.6, 12 ± 1, 11.7 ± 1, 10 ± 1 and 12.5 ± 1.3 µg ascorbic acid equivalents per millilitre for ZM1 to ZM8, respectively. Among these EOs, ZM3 with carvacrol and p-cymene had higher antioxidant, NO scavenging and MDA scavenging properties.
