Abstract
The essential oil of the aborted flowers of Vitex negundo var. heterophylla growing wild in Shijiazhuang was extracted by hydrodistillation and analyzed by gas chromatography-mass spectrometry( GC-MS). Twenty one constituents accounting for 94. 8% of the total oil were identified. The oil consisted mainly of β-caryophyllene( 42. 2%),sabinene( 12.2%) and 1,8-cineole( 5.5%),and can serve as a good source of β-caryophyllene.
