Abstract

Histochemical studies on the uropygial gland of domestic fowls have shown the presence of sterols (among which cholesterol and its esters) in the lipidic fraction of the gland secret. beta-Glucuronidase activity beside A5 3beta- and 17beta-hydroxysteroid dehydrogenase activities suggests that uropygial gland might be involved in sterols metabolism. By thin layer chromatography cholesterol and 7-dehydrocholesterol can be separated from the uropygial extracts and these compounds can be identified in gas liquid chromatography.

摘要

对家禽尾脂腺的组织化学研究表明，在该腺体分泌物的脂质部分存在甾醇（其中包括胆固醇及其酯类）。β-葡萄糖醛酸酶活性以及A5 3β-和17β-羟基类固醇脱氢酶活性表明，尾脂腺可能参与甾醇代谢。通过薄层色谱法，可从尾脂腺提取物中分离出胆固醇和7-脱氢胆固醇，并且这些化合物可在气液色谱法中得到鉴定。
