Abstract

To identify the antimicrobial activity, of tumeric and its active compound tumeric was fractionated into four groups dichloromethane extract, hexane fraction, methanol soluble fraction and residue's extract. They were tested for antibacterial activity against E. coil and S. aureus and the methanol soluble fraction was found lo be the most active fraction. Compound I, II and III were isolated from TLC and silica gel column chromatography in the methanol soluble fraction. These compounds were analyzed by $^1H-NMR\;and\;^{13}C-NMR$ spectra and identified as curcumin I, II and III. They were also tested for antimicrobial activity against E. coli and S. aureus. Curcumin I was the must active curcuminoids due to the phenolic and methoxyl$(OCH_3)$ moiety in the same molecular structure.
