Abstract
In order to study, non-enzymatic antioxidants level of carotenoid and ascorbic acid in parsley leaves of twenty-one masses were compared between the first and second harvest. Also for evaluation of enzymatic-antioxidant activity, catalase and peroxidase activity in leaves of two twenty-one masses were measured at the end of vegetative growth. In each replication, one gram of fresh mixed leaf tissue of all samples was selected to measure the above mentioned parameters based on standard methods. , The data were analyzed in a randomized complete block design by SAS software. Results showed that the highest and lowest levels of carotenoids in the first harvest were7.54 and 2.00 mg/100 g in Bushehr 149 and Lorestan 69 masses, respectively. The maximum and minimum levels of vitamin C in the first harvest were 0.733 and 0.039 mg/100g in Lorestan 153 and western Azarbaijan 51 masses, respectively. The highest and lowest peroxidase activity were found 3.25 and 0.11 micromole of hydrogen peroxide per minute in central mass 46 and control region (native Ahwazi) respectively. The highest and lowest catalase activity were related 0.645 and 0.006 micromole of hydrogen peroxide per minute to Eastern Azerbaijan 62 and Central 45. According to results of this study, Lorestan 153, Lorestan 69, and Hamadan 49 masses could be introduced as the best masses of antioxidant activity.
