title: Comparative study on the antioxidant activities of the different extracts and the composition of the oil extracted by n-hexane from Iranian Vitex pseudo-negundo.
abstract: Antioxidant activities of different extracts obtained from the aerial parts of Vitex pseudo-negundo from Kashan, central Iran, were evaluated for the first time in this study using β-carotene/linoleic acid and scavenging of free-radical (DPPH) assays. Water extract showed the highest activity in both assays. GC-MS analysis of the oil extracted by n-hexane revealed 46 compounds with trans-β-farnesene being the main component. Several new compounds, not reported in the previous literature, were identified in the essential oil of this chemo-type.
