Introduction: the species Moringa oleifera Lam., known as Moringa, has been introduced in Cuba mainly for nutritional purposes. However, no study has been reported about the fatty acid composition of the seed oil obtained from this species in Havana. Objective: determine the fatty acid composition of seed oil from M. oleifera plants growing in Havana, Cuba. Methods: the seeds were collected, milled and extracted with hexane in an ultrasonic bath. Extracts were filtered and the solvent evaporated. Fatty acids obtained from the oils were determined as methyl esters by gas chromatography with a BPX-70 capillary column. Results: the main fatty acids found were oleic (C18:1; 73.1%), palmitic (C16:0; 7.4%) and docosanoic (C22:0; 5.8%). Another 19 fatty acids, among them C12:0, C14:0, C15:0, C17:0, C18:1 (n-10), C18:2, C18:3, C20:0, C20:1, C21:0, C22:1, C23:0, C24:0, C25:0, C26:0 C27:0 and C28:0 were found in smaller proportions. This is the first report of the presence of acids C15:0, C27:0 and C28:0 in this species, and the first one to identify C12:0, C14:0, C17:0, C18:3, C20:0, C23:0, C25:0 and C26:0 acids in the species M. Oleifera growing in Cuba. Conclusions: oleic acid is the most abundant fatty acid component in seed oil from M. oleifera growing in Havana. This is the first report of the presence of acids C15:0, C27:0 and C28:0 in the seeds of this species, and of acids C12:0, C14:0, C17:0, C18:3, C20:0, C23:0, C25:0 and C26:0 in the species in Cuba. These results about the chemical composition of seed oil from the species M. oleifera could contribute to elucidate its potential nutritional usefulness.
