 Abstract: The chemical co nstitution of the seeds essential oil of Vitex kwangsiensis C. Pei and in vitro antioxidant activity ha ve been investigated. The essential oil was isolated by hydrodistillation method then analyzed by GC-MS. Fifty-six compounds were identified, representing 9 3.1 % of the oil. The main components identified were methyl linoleate (11. 2 %), caryophyllene oxide(10. 3 %), β-eudesmol (9. 1 %) and methyl palmitate (8. 1 %). The antioxidant activity was tested by DPPH method and it showed weak antioxidant activity. The composition and bioactivity of Vitex kwangsiensis seeds oil are described for the first time.
