We report the volatile composition of the body scent of male C57BL/6J mice in comparison to the volatile composition of their urine. From a total of 67 components, nitromethane, propanoic acid, dimethyldisulfide, 1-octene, 1-hexanol, hexanoic acid, indole, alpha- and beta-farnesene, and one unidentified component were observed only in the volatiles from the body of mice. On the other hand, 3-penten-2-one, 3-methyl-2-buten-1-ol, 3-methyl-cyclopentanone, p-xylene, 3-hepten-2-one, 2,3-dehydro-exo-brevicomin, benzylmethylketone, and 13 unidentified components were only found in urine volatiles. All other substances were present in the volatiles of both mice and their urine. Aliphatic aldehydes from pentanal to decanal were prominent mouse odor components. Because receptors for these aldehydes have been extensively characterized in the main olfactory organ, these components may be important for mice in recognizing their conspecifics.
我们报告了雄性C57BL/6J小鼠体香的挥发性成分，并将其与尿液的挥发性成分进行了比较。在总共67种成分中，仅在小鼠身体挥发物中观察到硝基甲烷、丙酸、二甲基二硫醚、1-辛烯、1-己醇、己酸、吲哚、α-和β-法尼烯以及一种未鉴定成分。另一方面，仅在尿液挥发物中发现了3-戊烯-2-酮、3-甲基-2-丁烯-1-醇、3-甲基环戊酮、对二甲苯、3-庚烯-2-酮、2,3-脱氢-外向-短叶松素、苄基甲基酮以及13种未鉴定成分。所有其他物质在小鼠及其尿液的挥发物中均有存在。从戊醛到癸醛的脂肪族醛类是小鼠的主要气味成分。由于这些醛类的受体已在主要嗅觉器官中得到广泛表征，因此这些成分可能对小鼠识别同种个体很重要。
