In the present investigation the antioxidant enzymes' activities and some antioxidant compounds' contents were studied in Fenugreek (Trigonella foenum graecum) under the effect of two different UV-doses for various times. The effect of two UV illumination doses (15 and 30 watt) was examined at different time intervals (1, 2, 3, 4 hr.). UV treatment enhanced the activities of antioxidant enzymes like superoxide dismutase (SOD, EC: 1.15.1.1), guaiacol peroxidase (GPX, EC: 1.11.1.7), glutathione reductase (GR, EC: 1.6.4.2), and ascorbate peroxidase (APX, EC: 1.11.1.11). The non-enzymic antioxidant compounds like reduced glutathione (GSH) and ascorbate were also raised. The higher dose 30 watt was more effective than 15 watt. Reactive oxygen species (ROS) formation like superoxide radical and hydroxyl radical is combined with many of morbid operations. Increasing the content of antioxidant defense system either antioxidant enzymes or antioxidant compounds get rid of the negative processes of reactive oxygen species (ROS).
