Chemical composition and antibacterial activities of ethanol extract of Arisaema langbiangense rhizome (Araceae)
2020
Overview
[...]12 compounds were found in the ethanol extract of A. langbiangense rhizome and the extract was proved to be able to inhibit the growth of Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Salmonella enteritidis, Salmonella typhimurium, Staphylococcus aureus. Bacterial strains The antibacterial activity of the extract was conducted using five bacterial strains, including two Gram-positive bacteria (Bacillus cereus (ATCC 11774), Staphylococcus aureus (ATCC 25923), and four Gram-negative bacteria (Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853), Salmonella enteritidis (ATCC 13976), Salmonella typhimurium (ATCC 13311). In mass spectrometer, the extract was then ionized using electrospray ionization source (ESI) at positive mode and the mass spectra data were recorded on mode for a mass range 50-2000 m/z. [...]there were 12 compounds present in the ethanol extract with similar molecular weights with compounds found in previous studies (Table 2).
