Cymbopogon, is a tall perennial grass with 55 species ofgrasses. Lemongrass is the source of Lemongrass oil, natural citral, which is used as a basic raw material for synthesis of β-ionone used for synthesis of a number of useful aromatic compounds and Vitamin-A. In the present study the determined plant parts (5g) of four CymbopogonSps. were ground, extracted with five solvents and filtered after 48hrs. The dry weight of the extracts was obtained by allowing the solvent to evaporate and was used to determine concentration in mg/ml. Microbial susceptibility assays using the agar dilution (Mueller-Hinton Agar) method (%v/v and corresponding mg/mL values) and the Minimal Inhibitory Concentration (MIC) were carried out for E.coli, Bacillus sp., Streptococcus sp., Staphylococcus sp.
