RESUMO

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

Palavras-Chave: Burseraceae; Protium; terpenóides; ácido 3,3'-di-0-metilelágico; ácido 3,3',4-tri-O-metilelágico

ABSTRACT

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

Key words: Burseraceae; Protium; terpenoids; 3,3'-di-0-metileIIagic acid; 3,3'-4-tri-0-methylellagic acid
