用~(14)C标记的2-甲基丙腈和2-甲基丁腈处理棉铃虫幼虫和幼虫成虫，并测定它们在生氰糖苷中的掺入量。这两个物种在测试的所有阶段都包含了前体，在15-72%的高水平上，从而表明在鳞翅目生物合成芳樟素和异亮氨酸的过程中，腈类化合物可能是中间体。
14C-labelled 2-methylpropanenitrile and 2-methylbutanenitrile were administered to larvae and imagines of Heliconius melpomone and to larvae of Zygaena trifolii and the incorporation into the cyanogenic glucosides, linamarin and lotaustralin, was measured. Both species incorporated the precursors at all stages tested, at a high level of 15-72%, thereby indicating that the nitriles are probable itermediates in the lepidopteran biosynthesis of linamarin and lotaustralin from valine and isoleucine respectively.
