Antibacterial Activity and Chemical Composition of Aquilaria malaccensis and Aquilaria sinensis Essential Oils

Abstract

Previous studies of antibacterial activity and chemical composition of Aquilaria malaccensis and Aquilaria sinensis essential oil were very limited number against Gram-negative and Gram-positive bacteria wound infections which are Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Aquilaria spp produce resinous portion, known as agarwood, that can be processed into essential oil and have been used in various sectors. For example, perfume industries, in religious ceremony, and medicine. Disk diffusion method done to observe the antibacterial activity by observing the formation of inhibition zone. Gas chromatography-mass spectrometry analysis used to identify the chemical composition that can interfere with and contribute antibacterial activity of A. malaccensis and A. sinensis. The purpose of the research is to determine the antibacterial activity against wound infection bacteria and identify the chemical composition of A. malaccensis and A. sinensis essential oils.
