Description
Summary:This study assessed the antistaphylococcal activity of essential oil (EO) hydrodistilled from the rhizome of Curcuma mangga grown in Indonesia using the broth microdilution volatilization method and standard broth microdilution method modified for evaluation of volatile agents, as well as described its chemical composition using gas chromatography (GC) with mass spectrometry (MS). A fused-silica HP-5MS column and a DB-17MS column were used to separate the components into two columns. The results demonstrated that the EO exhibited antistaphylococcal activity at the minimum inhibitory concentration (MIC) ranging from 128 to 1024 µg/mL. In contrast, the clinical isolate of tetracycline-resistant Staphylococcus aureus was the most sensitive strain (MIC 128 µg/mL). The major constituents of the EO were 15,16-dinorlabda-8(17),11-dien-13-one (24.63/15.78%), followed by ambrial (16.12/10.97%), 13-nor-eremophil-1(10)-en-11-one (7.16/6.21%), 15,16-dinorlabda-8(17),12-dien-14-al (6.61/11.57%), and aromadendrene oxide (5.98/3.77%). These results propose C. mangga rhizome EO as a promising agent for developing natural-based anti-infective preparations.
