Abstract. Typhonium lineare is a rare plant species of Typhonium genus and found only in Southern Vietnam. The species has not been any research on its phytochemical composition and antimicrobial activity. In present study, the chemical constituents and antibacterial activity of ethanolic extract of rhizomes and aerial parts of T. lineare was firstly investigated by Liquid chromatography–mass spectrometry (LC-MS) and disk diffusion methods, respectively. Consequently, six chemical constituents were reported from T. lineare aerial parts and rhizomes, including 5-(2’-methylpropyl)hydantoin, 5-(4’-hydroxybenzyl)hydantoin, uridine, cyclo(Leucyl-Tyrosyl), linolenic acid, gigantin and pheophorbide-a. Furthermore, the ethanolic extract of T. lineare rhizomes was not resistant to five studied bacteria whereas the extract from the aerial parts was proved to be able to resist against five bacterial strain, such as Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis and Salmonella typhimurium.
