Abstrakt
The relevance of this work lies in the fact of being the first phytochemical study realized with the species E. betulaceum and the isolated diterpenes are being described for the second time. So, the presence of diterpenes in E. betulaceum is in accordance with the chemical composition of the family.
These results indicated that E. betulaceum possesses similar chemistry with other species of this family, with the presence of labdanes and beyerane diterpene derivatives. From a chemotaxonomical point of view, these diterpenes together tropane alkaloids may serve as potential chemotaxonomic markers for Erythroxylum.
