Cinnamon is an important spice crop that is widely cultivated in tropical regions. In this study, the antibacterial activities of four accessions of cinnamon essential oil (CEO) belonging to three different species (CEO1 and CEO4, Cinnamomum cassia Presl. (Lauraceae) bark; CEO2, Cinnamomum zeylanicum Blume (Lauraceae) bark; CEO3, Cinnamomum burmannii Blume (Lauraceae) bark) toward Salmonella enterica subsp. enterica serovar pullorum (S. pullorum) were evaluated by microdilution assay and kinetic anal. The min. inhibitory concentration (MIC) of the CEOs were all 0.31 mg/mL, and kinetic anal. suggested that the lag phase and maximum specific growth rate of bacteria were concentration dependent. Furthermore, to explore the synergistic antibacterial effects between main components and minor components, the volatile constituents of CEOs were determined by gas chromatog.-mass spectrometry (GC-MS). Cinnamaldehyde (CM) (57.73 %-91.79 %) was the principal constituent in CEO1-CEO4 (p < 0.05), with CEO3 having the highest CM contents. A synergistic effect against S. pullorum was observed when CA was combined with CM. To explore the potential synergistic mechanism, the membrane glycerophospholipid (GPL) composition of S. pullorum was characterized by ultra-performance liquid chromatog.-tandem mass spectrometry (UPLC-MS/MS). CM, CA, and their combination regulated the levels of most phosphatidylethanolamines (PEs), phosphatidylglycerols (PGs), phosphatidic acids (PAs), and some cardiolipins (CLs). In the experiment, the researchers used 3-Chlorobenzylchloride(cas: 620-20-2Formula: C7H6Cl2)
3-Chlorobenzylchloride(cas: 620-20-2) has been used in the reaction of 3-methoxybenzyl chloride and ethyl 4-bromobenzoate in pure water, using zinc dust and a Pd catalyst.Formula: C7H6Cl2
