Micellar electrokinetic chromatography coupled to amperometric electrochemical detection was used to resolve and then quantify biogenic amines and metabolites within the fruit fly Drosophila melanogaster. A new separation scheme was devised to allow resolution of 24 compounds of interest. This was accomplished by precisely controlling the amount of base added to the background buffer, optimizing the resolution of the separation, and then calculating the pH. Here we focused on measurements of six of the analytes that are thought to be involved in the response to alcohol, dopamine, salsolinol, norsalsolinol, N-acetyloctopamine, octopamine, and N-acetyldopamine. These were identified and quantified within the fly head. We believe that the identification of salsolinol and norsalsolinol in the fly brain is novel.
胶束电动色谱与安培电化学检测联用,用于分离并定量果蝇果蝇体内的生物胺和代谢物。设计了一种新的分离方案,以允许分离 24 种感兴趣的化合物。通过精确控制背景缓冲液中添加的碱量、优化分离的分辨率,然后计算 pH 值来实现这一点。在这里,我们重点测量了六种被认为与酒精反应有关的分析物,包括多巴胺、salsolinol、norsalsolinol、N-乙酰氧基辛巴胺、章鱼胺和 N-乙酰多巴胺。这些物质在果蝇头部被鉴定和定量。我们认为在果蝇大脑中鉴定出 salsolinol 和 norsalsolinol 是新颖的。
