Summary: This study determined the chemical composition of Amomun tsao-ko essential oils (AEOs) from different regions using GC-MS and GC-IMS techniques. The main compounds were identified as terpenes and aldehydes. OPLS-DA analysis revealed distinct differences in AEOs from different regions, primarily in terpenes, aldehydes, and esters. Furthermore, AEOs showed strong antibacterial activity against Staphylococcus aureus, with specific compounds identified as potential antibacterial agents. This study provides a foundation for optimizing A. tsao-ko varieties and utilizing them as natural food preservatives.

Summary: This study analyzed the chemical composition of Centipeda minima essential oil (EOCM) using GC-MS, and found that the main constituents were trans-chrysanthenyl acetate, thymol, aromadendrene, and beta-caryophyllene. The antibacterial screening revealed that thymol and carvacrol, two monomers in EOCM, exhibited antibacterial activity against S. aureus. The minimum inhibitory concentrations (MIC) of EOCM, thymol, and carvacrol were 0.625 mg/mL, 0.156 mg/mL, and 0.156 mg/mL, respectively. The experimental results demonstrated that these three drugs could inhibit the growth of S. aureus and the formation of biofilm by altering the permeability of cell membrane and interfering with bacterial metabolic activities. The scavenging effects on DPPH radical and hydroxyl radical indicated that the antioxidant effect of the three drugs was EOCM > carvacrol > thymol.

Summary: This study analyzed the phytochemical composition and antibacterial activity of essential oils extracted from the rhizomes and aerial parts of Homalomena cochinchinensis for the first time. The essential oil from rhizomes inhibited the growth of all six tested bacterial strains, while the essential oil from aerial parts was effective against five bacterial strains. Key constituents in the essential oils were identified through gas chromatography-mass spectrometry.

Summary: The chemical composition of Origanum elongatum EO was analyzed, and its antioxidant, antibacterial, and insecticidal activities were evaluated. The main component of the EO was carvacrol (57.32%). The EO exhibited significant antiradical and reducing power, as well as considerable antibacterial activity against various pathogenic bacteria. It also demonstrated high efficacy as a fumigant insecticide. Therefore, O. elongatum EO could be used as a natural antioxidant, antibiotic, and biopesticide.
