ABSTRACT :- This research aims to study wild oilseed plants in the Moxico Province of Angola and assess the potential of using oils extracted from their seeds as an alternative to known oilseeds. Three such plants were identified: Mufuko, Mushi and Muthongo, whose ethnobotanical studies show greater resistance to drought and cold. Their respective seed yields per hectare are estimated at 4,800 kg/ha, 7,850 kg/ha, and 2,600 kg/ha. Gas chromatography coupled with mass spectrometry shows that the triglycerides are mainly composed of oleic, stearic and palmitic esters, with Mufuko having a more saturated carbon chain structure. The oil extraction yield from the seeds using Soxhlet and the solvent n-hexane is 94.50% for all three plants. The oil content of Mufuko, Mushi and Muthongo seeds is 33%, 42% and 52% respectively, exceeding that of conventional oilseeds such as palm, palm kernel, soybean, peanut, coconut and safflower by 45%, 30%, 20%, 50%, 22% and 42% respectively. The U.V. spectrophotometer shows that the salts content in their oils is 54.6, 60.6 and 41.6 ppm; the phosphorus content is 27, 113 and 64 ppm; and the nitrogen content is 229, 149 and 34 ppm, respectively. The phenol content exceeds 40 µg in the Mufuko plant.
