| Abstract: | The Chemical study of methanolic extract of the seeds from Erythrophleum ivorense led to the isolation of one original cassane diterpenoid (1) along with six known cassane diterpenoids (2–7). In addition, the known compounds (2–7) are isolated for the first time in E. ivorense. Their structures were established according to their spectral data (NMR, HRESIMS, IR). This result confirms that cassane-type diterpenoids are one of the major constituents of Erythrophleum species. The identification of these compounds and their chemotaxonomic significance is discussed. |
