Summary

Descripción general del contenido del recurso.

Three coumarins, 5-methoxypsoralene, xanthyletin, and (-)-marmesin, have been isolated from the ethanolic extract of the stem of the Amazonian plant Brosimum potabile. The structures were determined on the basis of NMR analyses and by comparison with spectroscopic data in the literature. The analysis of the hexane fractions by GC-MS in EIMS mode suggested the presence of (1-methylpentyl)-benzene; &#945;,&#945;-dimethyl-4-(1-methylethyl)-benzenemethanol; 1-methyl-3,5-bis(1-methylethyl)-benzene; urs-12-ene; chola-5,22-dien-3&#946;-ol; cholesta-4,6-dien-3&#946;-ol; sitosteryl 9(Z)-octadecenoate; cholesta-5,22-dien-3&#946;-ol; cholesta-4,6,22-trien-3-one; and cholesta-4,22-dien-3-one. NMR data of other hexane fractions indicated the presence of 3&#946;-acetoxy-lup-12,20(29)-diene; 3&#946;-acetoxy-olean-12-ene; 3&#946;-acetoxy-urs-12-ene; and adian-5-ene. All these compounds are first described in B. potabile.<br>Três cumarinas, 5-metoxipsoraleno, xantiletina e (-)-marmesina, foram isoladas no extrato etanólico do cerne da planta amazônica Brosimum potabile. Suas estruturas foram determinadas a partir das análises por RMN e por comparação com dados espectroscópicos da literatura. As análises das frações hexânicas por CG/EM sugeriram a presença de (1-metilpentil)-benzeno; &#945;,&#945;-dimetil-4-(1-metiletil)-benzenometanol; 1-metil-3,5-bis(1-metiletil)-benzeno; urs-12-eno; cola-5,22-dien-3&#946;-ol; colesta-4,6-dien-3&#946;-ol; (9Z)-octadecenoato de sitosterila; colesta-5,22-dien-3&#946;-ol; colesta-4,6,22-trien-3-ona e colesta-4,22-dien-3-ona. Dados de RMN de outras frações hexânicas indicaram a presença de 3&#946;-acetóxi-lup-12,20(29)-dieno; 3&#946;-acetóxi-olean-12-eno; 3&#946;-acetóxi-urs-12-eno e adian-5-eno. Todos esses compostos foram identificados pela primeira vez em B. potabile.
