Thegenus Xanthogalum is represented in the flora of Iran by just one species, namely Xanthogalum purpurascens. In this work, we report the antibacterial activity and the analysis of the leaf essential oil of X. purpurascens grown wild in Iran. The chemical composition of the essential oil from the leaves of X. purpurascens, collected from Mazandaran Province, were analysed by GC and GC/MS. Sixty-two components which representing 91.24% of the total composition were identified. 1,8-Cineole (17.59%, respectively), cis-muurol-5-en-4-α-ol (5.7%), neryl acetate (5.31%) and E-anethole (5.21%) were the main components in this oil.The antibacterial activities of the leaf oil of X. purpurascens were evaluated by disc diffusion method using Muller-Hinton Agar for bacteria with determination of inhibition zones and Minimal Inhibitory Concentration (MIC). The antibacterial activity showed that this oil had moderate Inhibitory against Klebsiella pneumonia. The leaf essential oil of X. purpurascens, was ineffective against Bacillus anthracis and Pseudomonas aeruginosa.
