of Al Jebel Al-Akhdar and the outly

of Al Jebel Al-Akhdar and the outlying mountains of Jebel Qubal and Jebel Al-Khawr [1]. Juniperus excelas is a shrub or tree up to 20 m tall with a trunk as wide as 2 m in diameter. Its crown is conical but later it becomes broader and open [2]. The leaves are evergreen and of two types. Seedlings develop needle-like leaves 8–10 mm in length, while adult trees grow scale-shaped leaves 0.6–3 mm long [3]. The main reported chemical components of the essential oil of the fruit are α-pinene (89.49%) and germacrene B (4.36%) [4] and [5], and the main chemical constituents of the essential oil of the leaves are cedrol (28.1%), α-pinene (22.5%) and limonene (22.7%) [6].

J. excelas is used in traditional medicine mainly for lowering blood pressure [4]. Its essential oil is also widely used in aromatherapy for mood scents, scent masks, soaps, candles, cosmetics and fragrances, lotions and remedies [5]. In Oman, it is also used traditionally for bronchitis, the common cold, jaundice and tuberculosis [7], [8], [9], [10], [11], [12], [13] and [14]. Other species of juniper are used for the treatment of hyperglycaemia, tuberculosis, bronchitis, pneumonia, ulcers, intestinal worms, wound healing and liver disease in traditional medicine [5]. In Turkish traditional medicine, juniper species are mainly used as diuretics, stimulants, antiseptics and for wound healing [8] and [9]. The essential oil of J. excelas is reported to have strong antimicrobial, antioxidant, antifungal, antiviral and antispasmodic activities [9], [10], [11], [12], [13] and [14]. The aim of this work was to isolate and identify the chemical constituents of the essential oil from fruit of J. excelas and evaluate their antimicrobial activity against foodborne pathogenic bacteria.
