The essential oils of unripe and ripe berries have been obtained by hydrodistillation and identified using GC/MS revealing significant difference in compositions between the two essential oils. Thirty two compounds (86%) and thirty compounds (86.81%) have been identified in the unripe and ripe barriers essential oils respectively. While trans-nerolidol (23.76%), (Z,E)-farnesol (22.2%), and α-pinene (21.8%) have been the major compounds of the unripe berries essential oil, α- pinene (44%) has been the major compound of the ripe berries essential oil in addition to other compounds like β- myrcene (6.99%), (E,E)-farnesol (4.66%), and β- pinene (4.57 %). Theantioxidant activities of the essential oils of green and ripe barriers, in addition to that of the positive control Butylated hydroxyltoulene (BHT) have been employed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. The results reveal limited antioxidant activities of the two essential oils compared to BHT.
