%X Essential oils from the leaves of Beackea frutescens were extracted by using three hydrodistillation methods, the Dean-Stark (DS), Clavenger (C) and simultaneous steam distillation extraction (SSDE). The yield of essential oils for each method was 0.32 %, 0.40% and 0.83%, respectively. The essential oils were examined using gas chromatogram and gas chromatography-mass spectrometry. Twenty constituent of the essential oils were identified. The major compounds were terpinolene (22.33%), t- -bisabolene (10.12%),  -cymene (9.85%), linalool (7.32%) and t-caryophyllene (6.06%),  -bergamotene (2.42%), nerolidol (1.35%). The pure essential oils obtained and four emulsion samples which contained 0.2-0.5% of the essential oils shown antibacterial activity against Staphylococcus aureus. The inhibition zones were 10.5 -17.0 mm. The inhibition zone exhibited by the emulsion samples varied dependent on the percentage of the essential oil used.
