Abstract Fresh twigs of Pluchea arabica (Boiss) Qaiser & Lack (Compositae) were steam‐distilled and the essential oil obtained was analysed by GC–MS. Forty‐four components were identified, accounting for 93.2% of the total components detected. The major constituents were δ ‐cadinol (26.8%), 9‐(1‐methylethylidene)‐bicyclo[6.1.0]nonane (10.8%), caryophyllene oxide (10.0%), methyleugenol (9.2%) and β ‐caryophyllene (6.9%). The essential oil of P. arabica was active against Staphylococcus aureus (ATCC 29213), Candida albicans (ATCC 10231) and Bacillus subtilis when tested against seven organisms. The oil was found to be less fragrant than Ocimum forskaoli oil in an odour test. Copyright © 2006 John Wiley & Sons, Ltd.
