Abstract

A second hypotensive agent from Verbesina caracasana is shown to be the truxinic type dimer of the previously isolated 3,4-dimethoxycinnamoyl guanidinoamide. The new compound gave by alkaline hydrolysis a crystalline monoamide, which in turn by acid hydrolysis gave 3′,4′-dimethoxy-β-truxinic acid, identical with a synthetic specimen. Title compound 1 gave by alkaline hydrolysis the monoamide 2 (R = OH), which in turn by acid hydrolysis gave a β-truxinic acid 3 (R = OH), identical with a synthetic specimen.
