Essential oil

Syzygium boisianum (Gagnep.) Merr. & L.M.Perry, locally named Tram bois, is widely distributed in primary or secondary forests of Vietnam, Thailand, and China. [6] For the first time, the current report provides information on chemical compositions in essential oil of S. boisianum leaves, collected from the northern part of central Vietnam. The obtained oil was also used to assess its antibacterial effects. The biological potential is highlighted by the molecular docking study.

The biological activities of E. ciliata essential oils (Ec EOs) in Vietnam have yet to be thoroughly studied and have received less attention than other species of genus Elsholtzia in the world. In this study, we evaluated the antioxidant, antimicrobial, and anticancer of Ec EOs and examined their chemical compositions. Fresh leaves of E. ciliata were hydro-distilled to yield essential oil of 0.82% dry weight, respectively.

The essential oils were also tested for their antioxidant, anti-imflammatory, antimicrobial and cytotoxic activities. The HD essential oil sample showed inhibitory activity against 6/8 tested microorganisms, i.e., Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Bacillus subtillis, Candida albicans, and Saccharomyces cerevisiae. The MHD and EHD exhibited the inhibitory activity against three strains E. coli, A. niger and F. oxysporum. The UHD inhibited E. coli and F. oxysporum.

In this continuity, the potentiality of D. citrea essential oil was subjected to screening research. The extract yield was obtained experimentally and its chemical characterization was acquired by gas chromatography-mass spectrometry (GC-MS). The determined data was subjected as the input for computational implementations, including density functional theory calculation, molecular docking simulation, and biopharma-potential predicting analyses.
