RESUMO:O estudo químico das frações neutra em hexano das folhas e em diclorometano do caule de Coccoloba mollis resultou no isolamento de um triterpeno pentacíclico (simiarenol), que pela primeira vez ocorre em Polygonaceae, dois fi toesteróides (sitostenona e sitosterol), um diterpeno (trans-fi tol) e de um benzenóide (ácido vanílico) que está sendo descrito pela vez neste gênero. A identifi cação estrutural destes compostos foi feita com base na análise dos dados espectrais (IV, EM e RMN, incluindo DEPT e HMQC), bem como pela comparação com dados descritos na literatura.Unitermos: Coccoloba mollis, Polygonaceae, triterpeno, benzenóide, fi toesteróides, diterpeno.ABSTRACT: "Chemical constituents from leaves and stem of Coccoloba mollis Casaretto (Polygonaceae)". This work describes the isolation of a pentacyclic triterpene (simiarenol), described for the fi rst time in this family, two phytosteroids (sitostenone and sitosterol), a diterpene (trans-phytol) and a benzenoid (vanillic acid), described for the fi rst time in this genus, from leaves and stem of Coccoloba mollis. These compounds were identifi ed on basis of their spectral data (IR, MS and NMR, including DEPT and HMQC), as well as by comparison with literature data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
