Abstract

The hexane-soluble fr. was found to be as intense in antifeeding activity as the crude methnol extract of Cryptomeria japonica against Acusta despesta. This hexane soluble-fraction was used to isolate and identify two sesquiterpenols, (−)-cubebol and (+)-2,7(14),10-bisabolatrien-1-ol-4-one, as the active compounds. Both compounds strongly inhibited the feeding behavior of A. despesta at 120 μg/cm2 and 80 μg/cm2 concentrations, respectively.
