Eight phenolic compounds were successively isolated and identified from the ethanolic extract of the
leaves of Faidherbia albida. Five of them were previously isolated from the genus Acacia, such as β-
amyrin (L-1), β-sitosterol (L-2), β-sitosterol-3-O-β-D-glucopyranoside.(L-3), Quercetin (L-5) and Gallic
acid (L-6), the other three are firstly reported for isolation from the genus Acacia, and named
Rhamnocitrin (L-4), Afzelin (L-7) and (6S, 9S)- Roseoside (L-8). The structures were identified and
confirmed through different spectroscopic methods including 1H-NMR, 13C-NMR, HMBC 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 ethyl acetate and aqueous fractions of the leaves.
