 and four vegetables (Spinach, Bitter leaf, Tomato, Pumpkin leaf) were selected from the Eastern part of Kogi State, Nigeria. DPPH radical scavenging activity was performed on each sample at four different concentrations (25µg/mL, 50µg/mL, 75µg/mL and 100µg/mL) and results were compared with Vitamin C. Our results revealed that the fruits had a higher radical scavenging activity than the vegetables. Judging by the mean DPPH scavenging activity, apple (77.73%) and tomatoes (58.16%) exhibited the highest radical scavenging activity in the vegetable and fruit category respectively. Taken together, the samples selected for study all possessed anti-oxidant activity; therefore, consumption of these vegetables and fruits is encouraged.&picture=http://www.aascit.org/aascit/decorators/img/journal/907.jpg)

DPPH radical scavenging activity is commonly used to assess antioxidant potential of biological materials. In this study, five fruits (Apple, watermelon, Sweet Garden egg, Bitter Garden egg, and Cucumber) and four vegetables (Spinach, Bitter leaf, Tomato, Pumpkin leaf) were selected from the Eastern part of Kogi State, Nigeria. DPPH radical scavenging activity was performed on each sample at four different concentrations (25µg/mL, 50µg/mL, 75µg/mL and 100µg/mL) and results were compared with Vitamin C. Our results revealed that the fruits had a higher radical scavenging activity than the vegetables. Judging by the mean DPPH scavenging activity, apple (77.73%) and tomatoes (58.16%) exhibited the highest radical scavenging activity in the vegetable and fruit category respectively. Taken together, the samples selected for study all possessed anti-oxidant activity; therefore, consumption of these vegetables and fruits is encouraged.
