High-performance liquid chromatographic analysis of monoamines in the cestode Diphyllobothrium dendriticum.
The presence of biogene monoamines in adult and larval Diphyllobothrium dendriticum (Cestoda) was investigated by high-performance liquid chromatography with electrochemical detection (HPLC-ED). The biogene amines serotonin (5-HT), dopamine (DA), noradrenaline (NA), and adrenaline (A) as well as many of their precursors and metabolites, comprising a total of 15 different substances, were analyzed. 5-HT, DOPA, DA, NA, and A were detected in the worm, with 5-HT, DOPA, and DA being the dominating amines. The DA metabolites DOPAC and 3-MT or the 5-HT precursor 5-hydroxytryptophan could not be detected, but two unidentified substances, believed to be catecholic, were present in the worm. A high concentration of DOPA was measured in the proglottids and especially in the eggs. This is the first report of A in a flatworm.
