对小野蚁和小野蚁雄蚁的提取物进行了分析。通过GC-MS和GC-FTIR对依贝尼铵的结构进行分析，发现存在酪酰胺2和4c，通过与合成样品进行比较确定了其结构。这些化合物和它们的类似物1和3也发现在雄性的其他Monomorium物种，雄性Myrmicaria opaciventris，和雄性的几个Solenopsis（Diplorhoptrum）物种。气相FTIR光谱揭示了两个酪胺，其中有甲基支化的酪胺酰基部分的非常重要的结构线索。酪酰胺4c显示出强的分子内酰胺NH氢键，其中推测酰基部分中存在α-酮基，并且还显示该酮基频率与酰胺νC=O的频率重叠。这些化合物的生物学功能尚不确定，但大量证据表明它们在蚂蚁交配行为中的作用。
Analysis of the extracts of male ants of Monomorium minimum and M. ebeninum, by GC-MS and GC-FTIR revealed the presence of tyramides 2 and 4c, for which the structures were established by comparison with synthetic samples. These compounds and their analogs 1 and 3 were also found in males of other Monomorium species, males of Myrmicaria opaciventris, and males of several Solenopsis (Diplorhoptrum) species. Vapor-phase FTIR spectra revealed critically important structural clues to two of the tyramides, which had methyl-branching in the tyramide acyl moiety. Tyramide 4c exhibited a strong intramolecular amide NH hydrogen bond where an α-keto group was deduced to be present in the acyl moiety and also showed the overlap of this ketone group frequency with that of the amide νC=O. The biological function of these compounds is uncertain; however their role in ant-mating behavior may be suggested by a large body of evidence.
