Abstract: Flowers of Jasminum sambac is widely used for decorative purposes as well as for the extraction of its highly aromatic essential oil. Studies had revealed biological activity potential of Jasminum sambac essential oil in terms of antioxidant, anticancer and antibacterial. The present study attempted to understand the bactericidal properties of Jasminum sambac essential oil against Staphylococcus aureus (ATCC 6538) and Pseudomonas aerugenosa (ATCC 27853) and mode of its action. Significant inhibition zones were obtained against both Staphylococcus aureus and Pseudomonas aerugenosa during disc diffusion assay. Minimum inhibitory and bactericidal concentration further supported the disc diffusion result. Estimation of leakage of reducing sugar, UV260 and UV280 absorbing materials suggested the deleterious effect of Jasminum sambac essential oil on bacterial membrane. The essential oil induced bacterial membrane damage was confirmed by studies on bacterial cell morphology using scanning electron microscopic method. Further studies are required to identify the active principle and to understand the underlying molecular mechanism of membrane damage caused by Jasminum sambac essential oil.
