Isolation, structural characterization and evaluation of the in vitro antioxidant potential of four compounds isolated from the selective leaf extracts of Bauhinia monandra Kurz (Fabaceae)

Bauhinia monandra belongs to Fabaceae family, is used in traditional Ivorian medicine treat diabetes and male infertility. A preliminary study conducted on the leaves, stems roots showed fluctuating contents of total phytophenols flavonoids ethyl acetate extract leaves. This made it possible isolate elucidate molecular structures four phytoconstituents from selective leaf extracts: Vomifoliol (1), guibourtinidol (2), epiafzelechin (3) D-pinitol (4). The were elucidated by NMR 1H, 13C, COSY, HMBC et HMQC. Also, There vitro antioxidant activity was measured using DPPH FRAP spectrophotometric methods.
