Research ArticleOpen accessIn the abstractEnhanced Antibacterial Activity of Blended Essential Oils against Staphylococcus Aureus and Methicillin-Resistant Staphylococcus AureusMin-Gi Kwon, Ji-Hyuk Kang, Jae Kyung KimWe aimed to evaluate the antibacterial effects of four blended and four single essential oils on the gram-positive bacterium Staphylococcus aureus (S. aureus) and methicillin-resistant S. aureus (MRSA). Minimum inhibitory concentration (MIC) testing was performed using disk diffusion and broth microdilution methods according to the Clinical and Laboratory Standards Institute criteria. The blended essential oils exhibited more powerful antibacterial activity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 16 Apr 2026 · 1,594 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Hydrodistillation Extraction by Response Surface Methodology and Evaluation of the Antioxidant and Antimicrobial Activities of Essential Oils from Phragmites communis (Cav) TrinXin-Tong Zou, Hong-Yuan Ma, Yu-He Li et al.The principal objectives of this study encompass three distinct aspects: firstly, to streamline the extraction process of Phragmites communis (Cav) Trin essential oil; secondly, to systematically analyze the essential oil’s chemical composition; and finally, to evaluate biological activity. Through the system optimization experiment, the optimal extraction process was determined: the crushing size was set to 10 mesh, the total solid-liquid … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Biological Profiles and Chemical Contents of Ethanolic Nest Entrance Extracts of Thai Stingless Bees Tetrigona apicalisTouchkanin Jongjitvimol, Sathirapong Kraikongjit, Pussadee Paensuwan, Jirapas JongjitwimolTetrigona apicalis is a species of stingless bees found in Lower Northern Thailand. They normally construct their nest entrances as an external structure for protecting themselves from enemies. Their biological properties have not well characterized yet. The objectives of this study were to evaluate the antibacterial, antifungal and anti-proliferative activities of their nest entrances. Samples were collected from four provinces … …OnLine Journal of Biological Sciences, Vol. 20, Issue 3 · 2 Nov 2020 · 6,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction, Partial Identification and Bioactivities of Total Flavonoids from Carex meyeriana KunthHongbiao Wang, Penghui Wang, Xiudong Yang et al.To date, knowledge associated with extraction, chemical constituents and bioactivities of Total Flavonoids from Carex meyeriana Kunth (TFCMK) that remains unclear. Therefore, this paper was designed to optimize the ethanol reflux extraction method by response surface methodology and determine the chemical constituents by Liquid Phase-Mass Spectrometry (HPLC-MS); additionally, the bioactivities including antioxidant, antibacterial and hemolysis test were also explored.
