| Abstract: | The investigation of a Carterothamnus species afforded in addition to known euparine derivatives four new diterpenes, all being labdane derivatives. The structures are elucidated by 1H-NMR-studies and by some chemical transformations. The chemotaxonomic situation is briefly discussed. The constituents of the Carterothamnus species show a distinct differentiation to those of the neighbouring groups; however, in addition they also indicate some relationships. |
