    • Abstract

       

      Chemotaxonomy of 12 taxa of the tribe Bignonieae investigated resemble one another in the presence of syringly radicals, caffeic acid, gentisic acid, vanillic acid unknown phenolic compound L(68/69) uniformly positive activity of polyphenolase and overlapping incidence of several classes of secondary chemical constituents, phenolic compounds and unusual (non-protein) amino acids. The quantified chemical data indicate that Bignonieae are homogenous taxon and the taxa are closely related. The present study does not support the creation of Pyrostegineae and Oroxyleae.
