Eremophilane derivatives and other constituents from Haeckeria species and further Australian inuleae
摘要:
From the aerial parts of two Haeckeria species, in addition to known compounds, 19 new eremophilan-12-oic acids, one being a seco-nor derivative, two eudesman-12-oic acids and three germacran-12-oic acids were isolated. The other species only gave known compounds which in part are of taxonomic relevance. The structures were elucidated by high field NMR spectroscopy. The chemotaxonomic aspects are discussed briefly.
