This study aimed to detect the secondary metabolites and chemical components in the freeze-dried extract of Ottochloa nodosa (Kunth) Dandy. In addition, discovering the extract could have potential as a bacterial inhibitor by determination of the minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) carried out in extracts. Determination of antimicrobial potential of freeze-dried extracts was conducted through phytochemical screening, gas chromatography-mass spectrometry (GC-MS) test, agar disc diffusion and broth dilution methods. The study shows this extract has bacterial inhibitors’ potential since it contained phytochemical compounds such as alkaloid, saponin, flavonoid and tannin, while 9 chemical components have been displayed through GC-MS analysis. The disc diffusion method was done at different concentrations, at 25, 50 and 100 mg/ml. The result also shows that the extracts are able to inhibit the gram-positive and gram-negative bacteria.
