Abstract:
The seed and fruit extracts of two different cultivars, a white and a green cultivar, were analysed to study the antioxidant, antimicrobial activities and the phytochemical compounds. Oxygen is an important element in the body and the excess amount causes free radical activity in the human body. The antioxidant activities of the different cultivars, both seed and fruit extracts were studied using total phenolic content by Folin-Ciocalteu method, total flavonoid content by the method adopted by Moussa et al. and by using FRAP, Thiobarbituric acid and phosphomolebdenum assays. It was found that seeds of the both cultivars exhibit higher absorbance values than the fruits and was understood to be also a provider of antioxidants for our body after consumption. The antibacterial test was conducted using E. coli strain for the seed and fruit extracts of both the cultivars. It was found that the zone of inhibition of the extracts were not as convincing as the zone of inhibition of the standard used as Almox 500g. So it was understood that the fruit and the seed do not contain much antibacterial properties. The phytochemical screening was carried out for the seed and fruit extracts of both samples. Little variance in the results obtained for the different cultivars might be the result of the cultivation in soils of different composition and nutrient content.
