“…Another phytochemical constituents in theses, three selected fruits juices are ascorbic acid. According to Rekha et al [33], ascorbic acid acts as a particular antioxidant by reducing ferric ions, this could reduced lipid peroxidation. Also, ascorbic acid could transfer the hydrogen atoms to oxygen.…”

Cadmium (Cd) is one of the most toxic heavy metal. Numerous tissues both in vitro and in vivo suggest that Cd induced lipid peroxidation. The presence of antioxidant can inhibit this process. This present study was designed to determine the effects of mango, papaya, and banana juices on malondialdehyde levels (MDA) during Cd exposure in vitro. The result of this study showed that there were a significant difference MDA level between three selected fruits juices. The result of this study also showed the significant differences MDA level between the concentration of each fruit juices. The highest correlation was found between banana juices and MDA levels with IC50 1.12 and followed by papaya and mango juices with IC50 1.37 and 3.87 respectively. The findings of this study suggest that the three selected fruits juices may exert its protective action against Cd-induced lipid peroxidation in liver homogenate in vitro possibly through its antioxidant mechanism.

“…In the recent years, there is an increasing interest in finding antioxidants of natural origin. The most effective antioxidants are flavonoids, and other phenolic compounds present in plants particularly in herbs, seeds, and fruits [36,37]. Okwu and Emenike 2007 screened phytochemicals of five Citrus species and revealed the presence of saponins, tannins, flavonoids, alkaloids, and phenols.…”

Objective: The current investigation was contemplated to evaluate the phytochemicals and in vitro antioxidant activities in peel and pulp of some commercially grown citrus fruits of South India, namely, lemon (Citrus aurantifolia), orange (Citrus reticulata), sour orange (Citrus aurantium), pomello (Citrus grandis), and citron (Citrus medica). Methods:The peel and pulp of the fruits were separated and subjected to cold extraction using 70% alcohol. The extracts obtained were screened for the presence of their phytoconstituents using various qualitative and further quantified for major constituents. Further, the in vitro antioxidant activity was assayed by different radical scavenging methods, namely, 2,2-diphenyl-1-picrylhydrazyl, superoxide anion, nitric oxide, lipid peroxidation inhibition, iron chelating activity, and reducing power assay at different concentrations.Results: All the citrus fruits have shown significant in vitro antioxidant activity for the parameters assessed, wherein peel extracts recorded superior antioxidant potential than their corresponding pulps. The broad range of activity of the extracts suggests that multiple mechanisms mediated by the phytoconstituents are responsible for the antioxidant activity. Conclusion:The study thus revealed that peel and pulp of citrus fruits are potential sources of bioactive compounds which are reflected in antioxidant activity and supports their health-promoting claims of plethora of investigations.
