Abstract:

Antioxidants act as a defence mechanism that protect against deleterious effects of oxidative reaction produced by reactive oxygen species (ROS) in a biological system. In the present study, antioxidant effects were evaluated in guava fruit (Psidium guajava L.) extracts of three varieties viz. Lucknow 49, Allahabad Safeda and Arka Kiran. The enzymatic antioxidant (catalase, superoxide dismutase and guatathione peroxidise) and non enzymatic antioxidant (vitamin A, vitamin C & vitamin E) activities were evaluated using reactive substance assay method. All the three extracts of guava varieties grown under salt affected soil possess the significant level of enzymic antioxidant activities. Among them SOD activity was found be high in Allahabad Safeda followed by Arka Kiran and Lucknow 49. Similar trend of CAT were observed in both Allahabad Safeda and Lucknow 49. Allahabad Safeda showed the maximum activity of GPX (1.61) followed by Arka Kiran (1.40) and Lucknow -49 (0.61). Non enzymatic antioxidants, Vitamin A content was found to be highest in Arka Kiran followed by Allahabad Safeda and the lowest level was found in Lucknow 49. The higher level of Vitamin C content was noted in Allahabad Safeda followed by Lucknow -49 and lower level was recorded in Arka Kiran. High vitamin E contents was observed in Allahabad Safeda (19.4 mg/ g tissue) followed by Lucknow 49 (17.53 mg /g tissue) and Arka Kiran (11.34 mg /g tissue). These findings reveal that guava fruits have potent antioxidant activities which may be responsible for its pharmacological effects.
