GC-Mass analysis of the volatile components and antioxidant activity of Prosopis farcta from tow areas of Iran

The volatile components of P. farcta (pods), growing wild in Zabol and Kashan, were analyzed by GC and GC-MS. Among components, which were identified,Octanoic acid (4.63%), Nonanoic acid (4.72%), Thymol (11.31%), Hexadecanoic acid (33.65%), oleic acid (22.04%) (Zabol), 1-Hexanol (4.59%), 3-Nonen-1-ol (4.96%), Nonanoic acid (4.65%), 2(3H) - dihydro-5-pentyl Furanone (9.95%), Hexadecanoic acid (16.93%) and oleic acid (12.15%) (Kashan) were the main constituents. But, in other report from Tunisia Methyl hexadecanoate, 9-Methyl octadecanoate, Phytol and 9-Ethyl octadecanoate were mentioned as major component. Antioxidant potential of the extracts were evaluated using Inhibition of hydrogen peroxide free radical that roots (Zabol area:IC50=14.12 μg/ml and Kashan area: IC50=10.72μg/ml) and branches (Zabol area:IC50=23.44μg/ml and Kashan area: IC50=14.70μg/ml) of the plant showed strong effectiveness in this antioxidant test. Total phenolic contents of the plant extracts were also measured by Folin-Ciocalteu reagent and results this test were parallel with antioxidant test.
