The dearth of information on the wood stem of Afzelia bipindensis led to the evaluation of its chemical, physical, phytochemical and functional groups analysis. Some obtained results from physical and thermal analysis were as follows; oven dry density 51.4 x 10-2 g.cm-3, water imbibitions (at different intervals: 30 min 22.2%, 5 h 37% & 24 h 59.1%), thermal conductivity 26.31 x 102 Umoh/cm, electrical conductivity 5.0 x 10-3 Sm-1, afterglow time 49.33Sec, flame duration 181.33Sec, flame propagation rate 4.6 x 10-2 cm.S-1, ignition time 8.33Sec, moisture content 20.28% and ash content 1.74% showed that it is a good timber that could be suitable for various construction purposes. Phytochemical screening showed the presence of saponins, tannins, steroids, flavonoids, carbohydrates, proteins, resins, terpenoids, glycosides and alkaloids. The AAS of the sample showed the presence of some metals such as Na, K, Pb, Ca, Zn, Mg, As and Cu in the decreasing order of their concentrations. The Thin Layer Chromatographic analysis showed two spots for chloroform extract. It was further characterized using Fourier Transform Infrared and Ultraviolet Spectroscopic methods which suggested a 1,2,3- trisubstituted phenylamide with NH, CO and CN groups attached as the functional groups present. The chemical components analysis showed the presence of cellulose, hemicelluloses, lignin and other constituents in their right proportion. The results confirmed the effectiveness of the wood for various construction purposes and its medicinal ability due to the presence of all the analyzed secondary metabolites.
