This study assessed the antibiofilm and antibacterial characterization of Curcuma longa rhizome extract against antibiotic-resistant foodborne pathogens. Gas Chromatography-Mass Spectrometry (GC-MS) and Fourier-transform infrared (FTIR) analysis were determined to check for the compounds, functional groups, and constituents of the plant extract. <i>In-vitro</i> antibiofilm and antibacterial bioassay of the extract were determined using standard bacteriological procedures.

The important chemical constituents from the GC-MS extract of <i>C. longa</i> are arturmerone, cinnamyl angelate, tumerone, γ-atlantone, atlantone, α-atlantone, γ-atlantone and curlone. The FTIR analysis of the extract comprises alkyl halides, bromoalkanes, alkanes, ethylene molecules, arenes, amines, alcohols, sulfones, carboxylic acids and their derivatives, aromatic compounds, and phenols. The MIC of <i>C. longa</i> crude extract ranges from ethanol extract (0.03125 - 0.5 mg/mL) and acetone extract (0.0625 - 0.5 mg/mL).
