We tested the inhibitory effects of a mint oil and it’s two volatile components on the growth of eight strains of fungi (i.e. Cladosporium spp., Aureobasidium spp. and Botrytis spp.) using direct contact experiment based on an agar medium dilution method. The minimal inhibitory concentration(MIC) of the oil to four NBRC’s strains (C. cladosporioides NBRC 6348, A. pullulans NBRC 6353,B. cinenerea NBRC 9760 and NBRC 30915) was 0.2-0.3% (v/v) at 25°C. MIC of ℓ-menthol was 0.3-0.5% (w/v) to the eight strains including Cladosporium sp. ANCT-11002, Aureobasidium sp. ANCT-11003, Botrytis spp. ANCT-06001 and ANCT-06022. On the other hand, menthone to 0.5%(v/v) concentration inhibited almost none of the growth of the all strains.
