Chemical profiles and antibacterial activities of acetone extracts of Globba macrocarpa

Globba macrocarpa Gagnep. is a rare species of genus (Zingiberaceae family). The present study reported the chemical compositions and antibacterial effects acetone extracts obtained from G. rhizomes aerial parts. By using Gas Chromatography Mass Spectrometry (GC/MS) assay, fifty thirty-two compounds were identified parts species, respectively. Of those, germacrene D (15.25 %), 1H-indole, 4-(3-methyl-2-butenyl)- (14.33 (E)-β-farnesene (11.28 2-biphenylamine, 3-methyl (10.27 %) major constituents in rhizome extract while part was characterized by predominance linolenic acid (19.89 palmitic (13.05 phytol (7.52 neophytadiene (4.76 %). In addition, had activities against five 5 out 6 oral bacteria, including Pseudomonas aeruginosa, Salmonella enteritidis, typhimurium Bacillus cereus, Staphylococcus aureus. Meanwhile, active 4 test except for Escherichia coli S. typhimurium.
