MetadataShow full item record
A re-investigation of Calea prunifolia afforded, in addition to compounds reported previously, a new eudesmanolide, a costol acetate hydroperoxide and four aromatic compounds. Calea peckii gave a large variety of aromatic compounds, three new bisabolene derivatives, a further guaianolide and, in addition to a known one, a further heliangolide. The structures were elucidated by high field NMR techniques.
