Withanolides from three species of the genus Deprea (Solanaceae). Chemotaxonomical considerations
Nine withanolides were isolated from the aerial parts of Deprea bitteriana, Deprea cuyacensis, and Deprea zamorae. D. bitteriana yielded two withaphysalins, D. cuyacensis gave two 13,14-seco withaphysalins, while D. zamorae yielded five physangulidines. The compounds were fully characterized by a co...

| Sumario: | Nine withanolides were isolated from the aerial parts of Deprea bitteriana, Deprea cuyacensis, and Deprea zamorae. D. bitteriana yielded two withaphysalins, D. cuyacensis gave two 13,14-seco withaphysalins, while D. zamorae yielded five physangulidines. The compounds were fully characterized by a combination of spectroscopic methods (1D and 2D NMR and MS). All compounds isolated from D. bitteriana and D. cuyacensis were obtained as epimeric mixtures at C-18. The structure of physangulidine D was confirmed by X-ray diffraction analysis. The skeletons found in this research support the chemotaxonomical position of the genus Deprea in the tribe Physalideae. |
