Essential oils were obtained by hydrodistillation of leaves, inflorescences and fruits of Vitex ugnus-castus L. (Verbenaceae). Yields ranged from 0.8 to 1.8% on dry weight basis. Eighty-five compounds were identified by GC-MS. The ratio of hydrocarbon : oxygen-containing components was nearly 1:l. 1

The chemical compositions of essential oils of some Piper species were determined by capillary GC and capillary GCยฑMS. Elemol (11.5%) constituted the most abundant component of Piper nigrum leaf oil, b-Caryophyllene (13%) was the major constituent of P. attenuatum leaf oil, whereas b-cubebene (10%)
The essential oils of fresh leaves, ยฏowers and fruits of Vitex agnus-castus L., growing in north Brazil, were obtained by hydrodistillation and their volatile constituents were identiยฎed by GCยฑMS. The most abundant constituents found were 1,8-cineole, (E)-b-farnesene, sabinene, a-pinene, a-terpenyl
