Chemical composition and antioxidant activity of Globularia alypum L. leaves essential oil from Ain-Defla (Algeria)

Abstract

The chemical composition of essential oil obtained by hydro-distillation with 2.10±0.09 % yield from dried Globularia alypum L. leaves was analyzed by GC-MS. It was determined 60 components representing 99.04 % of total oil. For the evaluation of the mentioned antioxidant activity, three different approaches were performed: the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, β-carotene bleaching (BCB) test systems and ferric reducing/antioxidant power assay (FRAP).The antioxidant was compared with that of synthetic antioxidant ascorbic acid. These findings indicate that the G.alypum essential oil exhibited good antioxidant properties.
