Resumen

Traditional medicine and studies with different species of the Prosopis genus, from the Sonoran Desert, is a source for the qualification of bioactive compounds, with antioxidant power and fatty acids (linoleic and linolenic) of the seed. The biological activity is attributable to alkaloids, flavonoids, terpenes and phenolic compounds, for which, the phytochemical profile was performed in the aqueous, ethanolic, hexane and chloroform extracts (using colorimetric techniques), antioxidant activity (method: 1,1-diphenyl-2-picrilhidrazil (DPPH)), total phenols (using the Folin-Ciocalteau reagent) and fatty acid profile (gas chromatography). The oil was extracted using Soxhlet. Saponins were found in all extracts, while, in ethanolic, hexanic and chloroform, terpenes and sterols. In the ethanolic extract quinones were found and in the aqueous free amino acids. The highest value of the antioxidant activity of EC50 was 3,272.41 ± 5.97, for the ethanolic extract, indicating its potential as an antioxidant. The total phenolic content was hexane> ethanol> chloroform> aqueous (81.95, 119.83, 125.18 and 127.57 mg equivalent of gallic acid / g of dry extract). The fatty acids in greater proportion were unsaturated with 71.41 % (linoleic acid: 42.68 %; oleic: 28.73 %) and saturated fatty acids: palmitic acid (13.42 %) and stearic (4.73 %). It is concluded that this type of extracts have important metabolites for the diet, have antioxidant activity and essential fatty acids for the body.
