title: Volatile constituents of Vitex negundo leaves.
abstract: Volatile constituents of Vitex negundo leaves growing in Dehra Dun (India) were analysed by gas chromatography-mass spectrometry (GC-MS) and showed the presence of sixty-six compounds. Such a study has not been done earlier on the Indian oil. Thirty-five compounds, constituting 74.96% of the oil, were identified. The main compounds are viridiflorol (19.55%), beta-caryophyllene (16.59%), sabinene (12.07%), 4-terpineol (9.65%), gamma-terpinene (2.21%), caryophyllene oxide (1.75%), 1-oceten-3-ol (1.59%), and globulol (1.05%). Viridiflorol is being reported for the first time in the oil of Vitex species.
