Constituents and Antibacterial Activity of Volatile Oil of Jasminum grandiflorum (Leaf) from Pakistan

Abstract

In this study, volatile composition and antibacterial activity of leaf of Jasminum grandiflorum were reported. The extraction was carried out by microwave that yielded 0.27% of oil. Gas chromatography mass spectrometry analysis led to the identification of 16 constituents where the most dominating compounds were: benzaldehyde (18.33%), caproic acid (5.70%), p-vinylguaiacol (5.58%), p-Ment-8-en-3-one (2.92%), and eugenol (2.59%)(Mills, 2000 #265). The antibacterial potentiality test was performed with the agar well diffusion method that revealed a considerable inhibition at 15.5 mg against Acinetobacter baumannii (12 mm), Escherichia coli (17 mm) and methicillin-susceptible Staphylococcous aureus (24 mm). The antimicrobial potential may be attributed to the occurrence of bioactive components such as benzaldehyde, jasmine, eugenol etc. that have established significance for pharmacological purposes.
