JARIPA BEGUM, MD. NAZRUL ISLAM BHUIYAN* AND TARANNUM TAZNIN

Abstract

The essential oil from aerial parts of Eupatorium triplinerve Vahl. was analyzed by gas chromatography mass spectroscopy(GC-MS). Thirty compounds representing 98.25% of the oil were identified. The major components were 2-tert-butyl-1,4-methoxybenzene (74.3%) and b-selinene (8.6%). The antimicrobial activity of the essential oil was evaluated against ten bacteria (including Gram positive and Gram negative) and six phytopathogenic fungi. The oil exhibited moderate antibacterial and strong antifungal activities against all the test pathogens. The highest antibacterial activity was recorded against Salmonella typhi (23mm) followed by Shigella sonnei (19mm) at a concentration of 20μl/disc. The highest antifungal activity was recorded against Macrophomina phaseolina (85%) followed by Botrydiplodia theobromae (84%) which are better in comparison with standard Nystatin.
