Deskripsi
<abstract language="eng">The chemical composition of two specimens of Esenbeckia grandiflora, collected in the south and northeast regions of Brazil, was investigated. 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, 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.
