Abstract: | Ten Prosopis chilensis populations from different phytogeografic areas of Argentina were analyzed chemically in their proximate and fatty acid composition. Oil and protein contents varied between 2.5–6.6% and 29.2–38.6%, respectively. Ash content ranged from 3.1 to 4.6%. The seed lipids contained a relatively large proportion of unsaturated fatty acids with linoleic acid as predominant. The results showed that: (a) There was a significant variation among populations in their chemical components, (b) moisture, ash and protein contents, and saturated fatty acids had not significant correlation with geographic parameters analyzed; (c) some unsaturated fatty acids correlated significantly with altitude. The variability observed might indicate that there is sufficient intraspecific differences to permit improvement by selection and breeding. |
