Evaluation of Proximate and Phytochemical Constituents of Pentadiplandra brazzeana Baill (“Osumada”) Roots





Pentadiplandra brazzeana Baill (Pentadiplandraceae) root is an ethnobotanical food spice used traditionally in the management of several disorders. However, the proximate and phytochemical constituents of P. brazzeana roots from Nigeria are not well documented. Therefore, this study was designed to evaluate the proximate and phytochemical constituents of P. brazzeana roots obtained from Agbor, Delta State, Nigeria. Proximate and quantitative phytochemical analysis of P. brazzeana roots were determined using standard procedures. Proximate analysis showed that P. brazzeana roots contained ash (3.27 ± 0.42 %), crude fat (6.87 ± 0.31%), crude fibre (9.41 ± 0.34%), moisture (10.66 ± 0.23%), crude protein (18.00 ± 0.51%) and carbohydrate (51.81 ± 0.82%). Quantitative phytochemical evaluation revealed the presence of alkaloids (0.02 ± 0.01%), saponins (0.41 ± 0.02%), flavonoids (10.14 ± 0.06%), tannins (1.54 ± 0.10 g TAE/100 g) and total phenolic (2.28 ± 0.01 g GAE/100 g) contents. Thus, the study showed that P. brazzeana roots could serve as an important source of nutritional and medicinal compounds. Further studies are recommended to investigate P. brazzeana root as potential source of food supplement and medicine to justify its ethnobotanical applications.
