Abstract

We have examined Agquilaria crasnna (agarwood) essential oil, leaf teas and various woody parts for their antibacterial effects. The pathogenic bacteria tested were 3 Gram-negative (E. coli, Enterbacter aerogenes, Pseudomonas aeruginosa) and 1 Gram positive (Staphylococcus aureus) one. We found the very antagonistic results from Agarwood essential oil in our study compared with the general knowledge that pure essential oils have significant antibacterial effects. However, in our study, we have found that optimum content of essential oil (40% essential oil diluted with DMSO) had better antibacterial effects than pure Agarwood essential oil. Other diluted percentages of Agarwood essential oil (pure, 20%, 60% and 80%) had no significant bacterial inhibition effects. Other parts of Agar wood (woody chips and leaves in form of teas) also had no significant antibacterial effects. Agarwood essential oil seemed to be more effective against Gram positive microbes but showed very weak or no anitibacterial effects against Gram negative microbial strains.
