A methanol extract of Cryptomeria japonica completely inhibited feeding by Locusta migratoria. Based on bioassay-guided fractionation, two active terpenols, (+)-ferruginol and (-)-cubebol, were isolated and identified as antifeedants against this insect species. Each compound separately showed weak activity, but they showed intense activity against this insect species when they were combined.
日本柳杉的甲醇提取物完全抑制了飞蝗的取食。基于生物测定导向的分级分离，两种活性萜烯醇，(+)-铁锈醇和(-)-荜澄茄醇，被分离并鉴定为针对该昆虫物种的拒食剂。每种化合物单独表现出较弱的活性，但当它们组合时，对该昆虫物种表现出强烈的活性。
