    Being widely used since its discovery, tobacco contains many chemical substances including nitric oxide, hydrocarbons, aldehydes, phenols, quinone and semiquinone radicals, and causes the formation of oxygen-induced free radicals directly or indirectly. Therefore, it is important to know the oxidant/antioxidant properties, phenolic content of Nicotiana rustica Linn., and the effect studies on Paraoxonase (PON 1) and Acetylcholinesterase (AChE) which are important metabolic enzymes. In the study, the effect of extracts (water and methanol) of Nicotiana rustica Linn on PON 1 and AChE enzyme activity was examined. Water extract of Nicotiana rustica Linn Maras Powder with walnut, (MPWW) and methanol extract Maras Powder with Nicotiana rustica, (MPNR), Maras Powder with walnut, (MPWW) and Maras Powder with copper cauldron, (MPCC) had an inhibitory effect on AChE (IC50 values in the range of 0.104-0.203 mg ml(-1)). Also water extract MPCC and methanol extract MPNR, MPWW and MPCC showed an inhibition effect on PON 1 (IC50 values 0.013-0.225 mg ml(-1)). MPNR water extract showed the highest activity with 26% DPPH radical scavenging activity. MPCC water extract showed a 13% ABTS radical scavenging activity.
