Abstract

Skin surface lipids from Equus caballus, E. przewalskii, E. asinus, E. grevyi, E. hemionus onager and a mule (E. asinus/E. caballus) were analyzed in detail. In all species the surface lipid mixtures consisted of giant-ring lactones, cholesterol, cholesteryl esters and minor amounts of wax diesters. In E. caballus, the lactone hydroxyacids were entirely branched chained, while in E. asinus and E. grevyi they were almost exclusively straight chained. In E. przewalskii, the onager and the mule there were both straight and branched chain hydroxyacid lactones. These results are in harmony with published interpretations of the evolutionary relationships among Equus species.

摘要

对家马、普氏野马、亚洲野驴、细纹斑马、藏野驴和一匹骡子（亚洲野驴/家马杂交种）的皮肤表面脂质进行了详细分析。在所有物种中，表面脂质混合物均由大环内酯、胆固醇、胆固醇酯和少量蜡酯组成。在家马中，内酯羟酸完全是支链的，而在亚洲野驴和细纹斑马中，它们几乎全是直链的。在普氏野马、藏野驴和骡子中，既有直链羟酸内酯，也有支链羟酸内酯。这些结果与已发表的关于马属物种进化关系的解释一致。
