- Abstract
Almond belong to Rosaceae family and itis a rich source of nutrients because of phytochemicals including phenolic compounds, phytosterols, flavonoids, phenolic acids, vitamins and fatty acids. In this study, we determined antioxidantactivities and phenolic, flavonoid, phytosterol, lipid soluble vitamin and fatty acid contents of almond kernel extract. Antioxidantactivity of almond extractwas investigated by DPPH, ABTS+, OH radical scavenging, metal chelating activity and determination of lipid peroxidation levels (TBARS). Almond extractscavenged 89.50% of the ABTS radical, 66.77% of the hydroxyl radical, and 87.30% of the DPPH radical. This extractshowed 72.05% of the metal chelating activity. Kaempferol (223.54 μg/g), naringenin (5.01 μg/g), vanillic acid (110.89 μg/g), caffeic acid (65.72 μg/g) and ferulic acid (16.49 μg/g) were determined in the almond extract. The major fatty acids were oleic acid (76.23%) and linoleic acid (15.43%). δ-tocopherol (3.05 mg/kg), α-tocopherol (104.40 mg/kg), and vitamin K (38.25 mg/kg) were determined in the almond extract. These results indicate thatalmond extractis a good natural source of fatty acids, lipid soluble vitamins, phytosterols, flavonoid, phenolic compounds. In addition, these findings are importantfor the nutrition sciences, because fatty acids, lipid soluble vitamins, phytosterols, flavonoid, phenolic compounds and antiradical properties, in particular, seem to have considerable effecton health.
