The study of antioxidant activity and composition of the oily compounds of leaves, extracted by n-hexane from Smirnovia iranica from central sandy areas of Iran

Smirnovia iranica Sabeti, is an adaptable plant of central sandy areas of Iran. This plant is very important because of many applications specially its application for grazing as a forage plant in sandy and dry lands of central Iran. The current research was carried out for the first one on determination of chemical components of oily compounds, extracted by n-hexane from Smirnovia iranica from Kashan, central Iran and antioxidant properties of polar methanol and non-polar n-heaxane extract of it. The results of GC-Ms analysis revealed 18 components with dodecanoic acid (10.83 %) and trans- β-ionone (10.04%) as the major components. Measuring antioxidant activity of the methanol and n-hexane extracts from S. iranica shows high activity in DPPH free radical scavenging and β-carotene bleaching assays for both extract. However methanol extract, exhibits stronger activities
