RESUMO

Dos extratos etéreo e etanólico da casca da madeira de Protium paniculatum Engl. foram isolados á e β-AMIRINA (0,012%), β-sitosiero! e estigmasterol (0,003%) e o ácido 3,3'-di-0-metilelágico (0,093%0). A presença do ácido 3,3',4-tri-0-metileIágico foi postulada com base na análise do espectro de massas.

Palavras-Chave: Burseraceac; Protium; terpenoídes; ácido 3,3'-di-o-metilelágico; ácido 3,3',4-tri-o-metilelágico

ABSTRACT

á- e β-myrin (0,012%), β-sitosterol and stigmasterol (0.003%),3,3'-di-0-methylellagic (0.093%) acid were isolated from the bark wood of Protium paniculatum. The presence of 3.3',4-tri-0-methylellagic acid was postulate on the of mass spectral analyses.

Key words: Burseraceae; Protium; terpenoids; 3,3'-di-o-metilelagic acid; 3,3'-4-tri-o-metilelagic acid
