San Joachin, Guasave, Sinaloa, México This research analyzed physicochemical parameters of lipids, as well as the fatty acid profile and diversity of three jojoba ecotypes of northwestern Mexico. Oil content was from 43 to 49% in the three ecotypes; iodine value ranged from 82.08 to 83.11 g / 100 g; acidity value was 0.33 to 0.39 mg KOH/g. The four most abundant fatty acids in the three ecotypes were eicosanoic (52-62.43%), oleic (13.80-27.36%), 13-docosanoic (5.25-9.45%), and palmitic (6.43-9.70%) acids. The Inter Simple Sequence Repeat (ISSR) analysis showed that polymorphic accessions were 83%. The ecotypes analyzed in this study represent an alternative for selection and conservation of wild germplasm; furthermore, they also represent a potential for their use in cosmetics and biodiesel manufacturing industries. http://pubs.sciepub.com/jfnr/5/6/12/jfnr-5-6-12.pdf fatty acid characterization ecotypes seeds
