The lipids of human and equine smegma pools were saponified and the total fatty acids submitted to temperature programmed gas chromatography (GC) analysis. In contrast to the human products, the horse smegma fatty acids contained very low odd saturated as well as olefinic branched chain acid contents. The cyclopropane fatty acid, 9,10-methyleneoctadecanoic acid, occurred in smegma sampled from men over 35 years of age but could not be detected in the pool from persons of 17-20 years of age nor in any of the equine mixtures. The alcoholic fraction from horse smegma contained about 85% sterol, the remainder constituting alcohols of C12 to C28 and of which 43.5% were branched chain components. The corresponding product from human smegma was primarily sterol. Squalene comprised the main hydrocarbon present in smegma of either species.
对人类和马的包皮垢样本中的脂质进行皂化处理，并将总脂肪酸进行程序升温气相色谱（GC）分析。与人类样本不同，马包皮垢脂肪酸中奇数饱和脂肪酸以及烯基支链酸的含量非常低。环丙烷脂肪酸9,10-亚甲基十八烷酸存在于35岁以上男性的包皮垢样本中，但在17至20岁人群的样本中以及任何马的混合物中均未检测到。马包皮垢的醇类部分约含85%的甾醇，其余部分为碳数12至28的醇类，其中43.5%为支链成分。人类包皮垢的相应产物主要是甾醇。角鲨烯是两种物种包皮垢中存在的主要碳氢化合物。
