Abstract

(R)-Terpinen-4-ol was mixed in an artificial diet at a concentration of 1 mg/g of diet, and the diet was fed to the last instar larvae of common cutworm (Spodoptera litura). Metabolites were recovered from frass and analyzed spectroscopically. (R)-Terpinen-4-ol was transformed mainly to (R)-p-menth-1-en-4,7-diol. Similarly, (S)-terpinen-4-ol was transformed mainly to (S)-p-menth-1-en-4,7-diol. The C-7 position (allylic methyl group) of (R)- and (S)-terpinen-4-ol was preferentially oxidized.

摘要

将（R）-松油烯-4-醇以1毫克/克饲料的浓度混入人工饲料中，并将该饲料投喂给斜纹夜蛾（Spodoptera litura）的末龄幼虫。从粪便中回收代谢产物并进行光谱分析。（R）-松油烯-4-醇主要转化为（R）-对-薄荷-1-烯-4,7-二醇。同样，（S）-松油烯-4-醇主要转化为（S）-对-薄荷-1-烯-4,7-二醇。（R）-和（S）-松油烯-4-醇的C-7位（烯丙基甲基）优先被氧化。
