Quantitative Bestimmung einiger biogener Amine in Bananen,Datteln und Feigen

Brands of bananas, dates, and figs were examined on the presence of serotonin, dopamine, noradrenaline, and adrenaline. Quantitative determination of the detected biogenic amines was performed by thin-layer chromatographic separation of their dansyl-derivatives followed by ultraviolet spectrophotometric measurement of the eluted substances. In bananas (eatable portion) could be found 77,5 µg/g serotonin, 650,5 µg/g dopamine, and 105,5 µg/g noradrenaline; in dates and figs only serotonin was detectable the amount of which has been 8,5 µg/g and 12,2 µg/g respectively.
