5-hydroxytryptamine in the Leaves of the Crown of Pineapple Fruit [Ananas comosus (Stickm.) Merrill]

Ivan Regula ; Hrvatska

Abstract

The leaves of the crown of Pineapple fruit were extracted with ethanol. The crude extract was purified with petroleum ether and passed through a column of Amberlite CG-50. The indole compound was investigated chromatographically and UV absorption spectrum (maxima at 275 nm and 295 nm), and fluorescence spectrum (550 nm when activated at 295 nm) were measured. On the basis of these data we conclude that the substance from the leaves of the crown is identical with an authentic sample of 5-Hydroxytriptamine and its quantity was 17.2 y/g fresh weight.
