Abstract: Five flavonoidal compounds were successively isolated and identified from the ethanolic extract of the fruits of Faidherbia albida. Two of them were previously isolated from the leaves of Faidherbia albida, such as Rhamnocitrin (F-1) and Quercetin (F-4), the other three are firstly reported for isolation from the fruit, and named Dihydrokaempferol (F-2), Luteolin (F-3) and Rutin (F-5). The structures were identified and confirmed through different spectroscopic methods including 1H-NMR, 13C-NMR and UV spectroscopy, in addition to comparison with authentic samples. Antioxidant activity was determined by the DPPH method revealed that all the tested extracts and fractions exhibited strong antioxidant activity especially the total ethanolic extract, chloroform and ethyl acetate fractions of the fruits.
