- Essential oil of aerial roots of Ficus elastica was extracted through hydro-distillation followed by separation by diethyl ether and dried over anhydrous sodium sulfate. Gas chromatography-mass spectrometry study of essential oil was performed to determine its chemical constituents. Fifteen constituents were identified and major constituents were benzene, [1-methyldodecyl] (9.96%); benzene, [1-ethynundecyl] (14.14%); 3,9 β, 14,15-di-epoxypregn-16-en-20-one (15.72%); benzene,[1-propyldecyl] (5.24%); 9,12,15-octadecatrienoicacid (6.76%); 2,3 bis[trimethylsilyl] 1-oxylpropylester (12.44%); 9,12,15-octadecatrienoic acid,2,3-bis[trimethylsilyl-oxy propylester (7.13%); octadec-9-enoic acid icosyl ester (7.07%) respectively. The antioxidant activity of the essential oil was measured by using DPPH and ascorbic acid as standard. The maximum antioxidant activity of the essential oil was 61.01% with 100 mg/ml while the antioxidant activity of ascorbic acid with similar concentration was 100%. Antioxidant prevents free radical induced tissue damage by preventing the formation of radicals, scavenging them, or by promoting their decomposition. Antioxidants obtained from natural resources are better for human health as they are less harmful.
