Abstract

The aim of this research was to examine ability of crude extract of mangosteen leaf to inhibit Aeromonas hydrophila and to determine the minimum inhibitory concentration (MIC) of crude extract of mangosteen leaf to inhibit A. hydrophila. In antimicrobial test against A. hydrophila by using agar well diffusion method with concentrations of crude extract of mangosteen leaf of 200,000 150,000 100,000 50,000 and 10,000 ppm, it was found that the crude extract of mangosteen leaf with the concentration of 200,000 ppm exerted the highest antimicrobial activity against A. hydrophila with the inhibition zone of 1.245±0.056 cm. Furthermore, from broth dilution assay, it was also found that the MIC of crude extract of mangosteen leaf against A. hydrophila was 1,563 ppm. The study demonstrated that mangosteen leaf, readily available throughout Thailand, could be used as an alternative for farmers to control the disease caused by A. hydrophila. This might help reducing the use of antibiotics having negative effect on environment.
