After the isolation of caracasanamide and caracasandiamide, further hypoten
sive components of Verbesina caracasana were shown to be N-3-prenylagmatine
, N-1-3',4'-dimethoxycinnamoylagmatine, agmatine and galegin (prenylguanidi
ne). The structures were assigned on the basis of the spectral data of both
metabolites and products from their alkaline hydrolyses. A pharmacological
analysis of these products is also presented. (C) 1999 Elsevier Science Lt
