%X New sources of edible oils extracted from new agricultural are continually researched. Mansa, Solanum americanum Miller, a typical culture widely produced in some african countries as Congo would be able to attaint this purposes. Mansa seeds contains up to 35% w/w of oil extracted by solvents, 2.7% in roots and 1.3% in leaves. The major fatty acid is linoleic acid (66.5%) followed by oleic acid (14.6%) and palmitic acid (12.6%). The minor fatty acids are DHA and EPA (0.17 and 0.23%, respectively). The omega 6/3 ratio ( 6/3) is lower than 5. Enzymatic extractions by pectinase yield 18% w/w of oil. Besides this lower oil extraction compared to solvent extraction, the enzymatic extraction would be interesting as a way to maintain the minors fractions contents of great functional activities since these minors  fractions are generally susceptible of heat oxidation.
