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, gamma-terpienene), ZM7 (thymol, p-cymene, gamma-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 mu g 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 mu g 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 mu g 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.
