Abstract
The essential oils (EOs) of the tubers and aerial parts of Cyperus alternifolius Rottb. were separately extracted and analyzed by gas chromatography-mass spectroscopy (GC-MS). Seventeen and fifteen volatile compounds were identified from the tubers and aerial parts represented 99.16% and 100% of the total mass, respectively. Terpenes (97.82% and 97.43%) were the more characteristic content including sesquiterpenes (97.22% and 3.89%) and monoterpenes (0.6% and 93.54%), respectively. Caryophyllene (50.6%), caryophyllene oxide (29.84%), farnesyl acetone (4.65%) represented the major components of the tubers EO. While D-limonene (63.78%), theaspirane A (13.36%), theaspirane B (10.97%) and γ-terpinene (3.4%) were the majors of aerial parts EO. The aerial parts oil showed significant antioxidant activity at all concentrations in relation to rutin by TLC-DPPH radical scavenging activity method. The EO of the tubers exhibited moderate antioxidant activity at 5 μg/ml and 10 μg/ml with values 1.33±0.13 and 1.12±0.38, respectively. Significant antioxidant activity were exhibited by aerial parts EO at the three concentrations 2.5 μg/ml, 5 μg/ml and 10 μg/ ml with activity values 5.83±0.61, 7.18±0.81 and 8.48±1.30, respectively.
