The physicochemical properties of the exudate of Dacryodes edulis and those of the saponification and acid hydrolysis products have been determined. The value of the purified exudate, acid hydrolysis product and saponification product where respectively: melting point (oC) (73.33, 62.20, and 60.33): flash point (oC) (110, 100, 100): Charring point (oC) (200, 190. 190) and density (g/cm3) (0.75, 0.88, 0.95). The exudate has a high intrinsic viscosity. The chemical constituents of the exudates gum were determined using standard methods. It was found that n-hexane was the most suitable solvent for purifying the exudate and for dissolving the modified products which were insoluble in water. The TLC Rf value of the purified exudate extracts shows that exudate is a mixture of many chemical substances while IR spectra indicate the presence of –COOH (carboxylic), -OH (alcohol), N-H and C-N (protein) functional groups in the purified exudate, acids hydrolysis and saponification products, suggesting the presents of resin acid, fatty acid, fatty alcohol and protein.
