Abstract: In this study microwave-assisted petroleum ether/ethanol two-phase solvent extraction was applied to extract the essential oil from the fermentation broth of Taiwanofungus camphoratus, and the minimal inhibitory concentration(MIC)of the essential oil against 7 species of dermatophyte were determined. The optimized extraction conditions are as following:ethanol concentration 56%(v/v), petroleum ether concentration 30%(v/v), solid-to-liquid ratio 1:50, microwave power 380 W and microwave time 90 s. The highest yield of extracted essential oil was 0.69%, and the MIC against the tested fungi were 5-20 mL/L. This extraction technology is efficient and time saving, moreover, the produced essential oil shows significant inhibitory effect on the growth of the tested dermatophyte.
