Physicochemical characterization of Coulaedulis oil was carried out using chemical analysis methods recommended by the Association Française des Normes (AFNOR) and the Association of Official Analytical Chemists (AOAC). The chemical profile of fatty acids in C. edulis oil was defined by gas chromatography.

The seeds of this plant have a medium oil content, and its acid value is within the Codex Alimentarius standards. Its iodine value is similar to that of semi-siccative oils. The saponification value of C. edulis seed oil is comparable to that of edible oils such as soybean, peanut and cotton. Depending on the value of its refractive index, this oil is classified as semi-siccative, like olive oil.

C. edulis oil contains a very high level of monounsaturated fatty acids, as its oleic acid content exceeds that of olive oil (Oleo europeae). This plant therefore needs to be industrially exploited, as it has great economic potential.
