Abstract:

A total of fourteen (14) species of wild edible fruits from Burkina Faso wereanalyzed for their phenolic and flavonoid contents, and their antioxidant activities usingthe DPPH, FRAP and ABTS methods. The data obtained show that the total phenolic andtotal flavonoid levels were significantly higher in the acetone than in the methanol extracts.Detarium microcarpum fruit had the highest phenolic and the highest flavonoid content,followed by that of Adansonia digitata, Ziziphus mauritiana, Ximenia americana andLannea microcarpa. Significant amounts of total phenolics were also detected in the otherfruit species in the following order of decreasing levels: Tamarindus indica > Sclerocaryabirrea > Dialium guineense > Gardenia erubescens > Diospyros mespiliformis > Parkiabiglobosa > Ficus sycomorus > Vitellaria paradoxa. Detarium microcarpum fruit alsoshowed the highest antioxidant activity using the three antioxidant assays. Fruits with highantioxidant activities were also found to possess high phenolic and flavonoid contents.There was a strong correlation between total phenolic and flavonoid levels and antioxidantactivities.
