代谢
当连续通过胃管(50毫克悬浮在阿拉伯树胶水中)给予大鼠(未指明品种)1-羟基蒽醌时,发现其被吸收,并且通过纸色谱法鉴定出了其代谢物。在处理后的48小时内收集尿液和粪便,并使用二乙醚进行提取。原本存在的1-羟基蒽醌中有2.49%和0.74%分别转化为尿液和粪便中的茜素(1,2-二羟基蒽醌)。之后,茜素在硫酸化和葡萄糖苷酸化后被排出体外。
... 1-Hydroxyanthraquinone was found to be absorbed when continuously administered to rats (strain not specified) by stomach tube (50 mg suspended in aqueous gum arabic), and its metabolites were identified by paper chromatography. Urine and feces were collected during 48 hours after treatment and extracted with diethyl ether. Of the 1-hydroxyanthraquinone originally present, 2.49% and 0.74% were converted into alizarin (1,2-dihydroxyanthraquinone), in urine and feces, respectively. The alizarin was then excreted after sulfation and glucuronidation.
