Gas chromatography/mass spectrometry was used to identify 103 organic compounds from urine, feces, anal glands, and preputial glands of free-ranging African wild dogs, Lycaon pictus. Aliphatic acids were the dominant class of compound in all materials. In addition to aliphatic acids, urine contained dimethyl sulfone, 1,3-propanediol, benzoic acid, 1-methyl-2,4-imidazolidinedione, and squalene as major components: feces contained indole and cholesterol; and both contained 2-piperidone, phenol, 4-methyl phenol, benzeneacetic acid, and benzenepropanoic acid and other compounds. Anal gland secretion was particularly rich in cholesterol and fatty acids, and preputial gland secretion rich in squalene. A large majority of the identified compounds have been reported from other mammals, including species sympatric with African wild dogs. Eleven of the African wild dog components have not been reported previously from mammals and have not been found in sympatric species; one component, 1-methylimidazole-5-carboxaldehyde has not been reported previously as a natural product. In the chemical profiles of their urine, feces, and anal gland secretion African wild dogs differ markedly from other canids.
采用气相色谱/质谱联用技术从自由放养的非洲野犬（Lycaon pictus）的尿液、粪便、肛门腺和包皮腺中鉴定出 103 种有机化合物。所有材料中均以脂肪族酸为主。除脂肪族酸外，尿液中还含有二甲亚砜、1,3-丙二醇、苯甲酸、1-甲基-2,4-咪唑烷二酮和角鲨烯等主要成分；粪便中含有吲哚和胆固醇；两者均含有 2-哌啶酮、苯酚、4-甲基苯酚、苯乙酸和苯丙酸等其他化合物。肛门腺分泌物特别富含胆固醇和脂肪酸，包皮腺分泌物富含角鲨烯。已从其他哺乳动物（包括与非洲野犬同域的物种）中报道了绝大多数已鉴定的化合物。非洲野犬的 11 种成分以前从未在哺乳动物中报道过，也未在同域物种中发现；一种成分 1-甲基咪唑-5-甲醛以前也未作为天然产物报道过。在尿液、粪便和肛门腺分泌物的化学特征上，非洲野犬与其他犬科动物有明显的不同。
