两种单倍体千足虫的防御异素是由以下三种硝基化合物（2-硝基乙基）苯和(Z)-和(E)-（2-硝基乙基）苯混合而成的。将2h标记的(Z)-和(E)-苯乙醛肟和2h标记的苯乙腈混合物作为前体，在两种物种中产生相同的三种2h标记的硝基化合物，[2'-硝基][2,3,4,5,6- 2h5]苯和[(Z)-和(E)-2'-硝基][2,3,4,5,6- 2h5]苯。以适当剂量施用肟可比施用腈更有效地产生具有相似自然比率的三种硝基化合物。在给药期间证明了从肟到腈的转化，反之亦然。选择离子色谱法在千足虫提取物中偶有检测到三种前体（Z-肟、e -肟和腈）。
The defense allomones of two haplodesmid millipedes, Eutrichodesmus elegans and E. armatus (Polydesmida: Haplodesmidae), are known as a mixture of the following three nitro compounds: (2-nitroethyl)benzene and (Z)- and (E)-(2-nitroethenyl)benzenes. Administrations of a mixture of 2H-labeled (Z)- and (E)-phenylacetaldoximes and of 2H-labeled phenylacetonitrile as precursors resulted in the same production of three 2H-labeled nitro compounds, [2'-nitroethyl][2,3,4,5,6-2H5]benzene and [(Z)- and (E)-2'-nitroethenyl][2,3,4,5,6-2H5]benzenes, in both species. Oxime administration at an appropriate dose resulted in the production of three nitro compounds with similar natural ratios more effectively than nitrile administration. Conversion from oximes to nitrile and vice versa was evidenced during administration. Occurrences of three precursors (Z- and E-oximes and nitrile) were detected sporadically in millipede extracts by selected ion chromatography.
