The essential oil of Mondia whiteï dry roots (Hook, f.) Skeels, harvested at Kindamba, in the Pool Department, south of Congo Brazzaville was extracted by hydrodistillation with a yield of 0.50%. Gas chromatography (GC) and gas chromatography-mass spectrometry (GC / MS) were used to characterize the chemical profile of the gas chromatography, then it was subjected to physicochemical analyzes. The physical and chemical properties evaluated were the refractive index and the acid number. The values of the refractive index in ether and in acetone are respectively 1.3703 and 1.3713 that of the determined acid number is zero.
Taking into account the high proportion of 2-hydroxy-4-methoxy-benzaldehyde (99.85%), this oil could be a source of production of 2-hydroxy-4-methoxy-benzaldehyde useful for agri-food needs and a formulation necessary for Pharmaceutical industry.
