Química Nova, 2009,32(8):2034-8. | Indolopyridoquinazoline alkaloids from Esenbeckia grandiflora mart. (Rutaceae).[Reference: WebLink] | The chemical composition of two specimens of esenbeckia grandiflora, collected in the south and northeast regions of brazil, was investigated.
METHODS AND RESULTS:
In this study, three β-indolopyridoquinazoline alkaloids from the leaves (rutaecarpine, 1-hydroxyrutaecarpine) and roots (euxylophoricine d) were isolated for the first time in this genus. in addition, the triterpenes α-amyrin, β-amyrin, α-amyrenonol, β-amyrenonol(beta-Amyrenonol), 3α-hydroxy-ursan-12-one, and 3α-hydroxy-12,13-epoxy-oleanane, the coumarins auraptene, umbelliferone, pimpinelin, and xanthotoxin, the furoquinoline alkaloids delbine and kokusaginine, and the phytosteroids sitosterol, stigmasterol, campesterol and 3β-o-β-d-glucopyranosylsitosterol were also isolated from the leaves, twigs, roots and stems of this species. structures of these compounds were established by spectral analysis. |
