The concentrations of catecholamines were determined in the decuticalarized retinas and brains at different ages in wildtype and ebony Drosophila melanogaster using the HPLC-technique with an electrochemical detector. L-Dopa, dopamine (DA), alpha-methyldopa (alpha-MD) and unidentified compounds X1, X2 and X3 were found in decuticalarized retinas and brains of wildtype and ebony at different ages. Retinas and brains of the mutant ebony have higher concentrations of L-Dopa, DA and alpha-MD than the wildtype. In both wildtype and ebony, the concentrations of X1, X2 and X3 were found to be higher in decuticalarized retinas than in brains. The identity and importance of X1, X2 and X3 are still unknown.
采用带有电化学检测器的高效液相色谱技术，测定了野生型和乌木型黑腹果蝇不同年龄去角质化视网膜和大脑中儿茶酚胺的浓度。在野生型和乌木型果蝇不同年龄的去角质化视网膜和大脑中发现了左旋多巴、多巴胺（DA）、α-甲基多巴（α-MD）以及未鉴定的化合物X1、X2和X3。突变型乌木果蝇的视网膜和大脑中左旋多巴、多巴胺和α-甲基多巴的浓度高于野生型。在野生型和乌木型果蝇中，去角质化视网膜中X1、X2和X3的浓度均高于大脑。X1、X2和X3的特性和重要性仍然未知。
