Antimicrobial properties from essential oils of Michelia alba

Nor;aishah A. S., . and Maheran A. A., . and Radzali M., . (2004) Antimicrobial properties from essential oils of Michelia alba. [Proceedings Paper]

In recent years in an attempt to discover new antimicrobial compounds many different sources have been explored including the higher plant essential oil. In the present study essential oils from flowers and leaves of Michelia alba were investigated for their bioactivites against several selected pathogenic bacteria and fungi using disc diffusion method and broth microdilution assay. Pathogenic fungal with higher inhibition zone were found more susceptible to this particular extract compared to the pathogenic bacteria. Meanwhile essential oil extracted in dichloromethane by hydrodistillation technique using SDE were managed to inhibit P. aeruginosa when other extract showed no inhibition. The lowest minimum inhibitory concentrations MIC were 0.625 mg/ml oil against Staphylococcus aureus and Bacillus subtilis compared to 0.039 mg/ml streptomycin as reference standard. These interested findings actually proof the past traditional practice of leaves of M. alba used as a treatment on abscess and as an another source of future biopharmaceuticals and biopreservatives agents.

Abstract

In recent years in an attempt to discover new antimicrobial compounds many different sources have been explored including the higher plant essential oil. In the present study essential oils from flowers and leaves of Michelia alba were investigated for their bioactivites against several selected pathogenic bacteria and fungi using disc diffusion method and broth microdilution assay. Pathogenic fungal with higher inhibition zone were found more susceptible to this particular extract compared to the pathogenic bacteria. Meanwhile essential oil extracted in dichloromethane by hydrodistillation technique using SDE were managed to inhibit P. aeruginosa when other extract showed no inhibition. The lowest minimum inhibitory concentrations MIC were 0.625 mg/ml oil against Staphylococcus aureus and Bacillus subtilis compared to 0.039 mg/ml streptomycin as reference standard. These interested findings actually proof the past traditional practice of leaves of M. alba used as a treatment on abscess and as an another source of future biopharmaceuticals and biopreservatives agents.
