Abstract Using gas chromatography (GC) in conjunction with electron impact mass spectrometry and retention-time comparison, 94 compounds, ranging from 2-methyl-2-propenal to octadecanoic acid, were identified in the interdigital secretions of male and female black wildebeests, Connochaetes gnou (also known as the white-tailed gnu). The constituents of these secretions belong to many different compound classes, including hydrocarbons, alcohols, aromatics and aliphatic carbonyl compounds including carboxylic acids as well as carboxylic acid esters. Relatively small quantitative differences were found between the male and female interdigital secretions. It was concluded that these compounds probably do not play a significant role in territorial marking or in chemical communication between males and females of the species, but they could be involved in preserving the remarkably strong attachment between members of social subgroups in black wildebeest populations.

哺乳动物外分泌物 XIX。黑角马 Connochaetes gnou 叉指分泌物的化学特征

摘要 使用气相色谱 (GC) 结合电子轰击质谱和保留时间比较，在雄性和雌性黑色角马 Connochaetes 的叉指分泌物中鉴定了 94 种化合物，范围从 2-methyl-2-propenal 到十八烷酸。牛（也称为白尾牛）。这些分泌物的成分属于许多不同的化合物类别，包括碳氢化合物、醇类、芳香族化合物和脂肪族羰基化合物，包括羧酸和羧酸酯。在男性和女性的趾间分泌物之间发现了相对较小的数量差异。得出的结论是，这些化合物可能在该物种的雄性和雌性之间的领土标记或化学交流中没有发挥重要作用，
