- Abstract
- Antimicrobial activity of UlGeum (Curcuma longa L.) was investigated. Methanol extract of dried UlGeum was fractionated to hexane, chloroform, ethyl acetate, butanol and water fraction. The antimicrobial activity of five crude fractions were examined using impregnated paper disk agar diffusion. Ethyl acetate fraction showed the highest inhibitory effect on the microorganisms such as B. subtilis, S. aureus, E. coli, L. monocytogenes and V. parahaemolyticus at 1,000 μg/disc. Ethyl acetate fraction was further fractionated by silica gel column and thin layer chromatography (TLC). The antimicrobial compound was isolated from their fractions and its chemical structure was identified as a 2,3-dihydrobenzofuran by GC-MS and 1H-NMR.
