A reinvestigation of Aristeguetia buddleaefolia gave 16 new labdanes and two nor-labdanes, while A. glutinosa afforded, in addition to large amounts of 8,15-dihydroxylabdane, three new nor-labdanes.Badillao salicina gave six new cis-clerodanes and Grosvenoria rimbachii, guaianolidines and tremetone derivatives, four of which are new.The structures were elucidated by high field NMR techniques and a few chemical transformations.The chemotaxonomy is discussed briefly.Key Word Index - Aristeguetia buddleaefolia, A. glutinosa; Badillao salicina, Grosvenoria rimbachii; Compositae; diterpenes; labdanes; nor-labdanes; clerodanes; tremetone derivatives.
