Abstract

Chemical Composition and Antioxidant Activity of the Essential Oil and Extracts of Dorema Glabrum Roots, Leaves and Flowers

The chemical composition of the essential oils obtained from Dorema glabrum (Umbelliferae) roots, leaves and flowers were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometery (GC-MS). About 37, 35 and 58 compounds were identified in roots, leaves and flowers of Dorema glabrum (D. glabrum), respectively. Essential oils of leaves were rich in sesquiterpenes (64.94%) and monoterpenes (5.17%), with β-caryophyllene (35.06%) as major component. Roots’s essential oil was rich in sesquiterpenes (55.18%) and monoterpenes (18.35%), with δ- cadinene (18.88%) as major component. And finally, flowers essential oil was rich in monoterpenes (58.31%), and sesquiterpenes (29.18%) with carvon (25.97%), germacrene B (13.05%) and α-limonene (10.37%) as major components. Antioxidant activity of the extracts of D. Glabrum roots, leaves and flowers have been studied by ferric reducing antioxidant power (FRAP) and2.2-diphenyl-1-picryl-hydrazyl (DPPH) assay. The obtained results show that the weakest (27.41% at μg/mL) and strongest radical scavenging activity (45.0% at 1 μg/mL) were exhibited by the D. glabrum roots’ and flowers’ methanol extract, respectively.
