ABSTRACT

- and -amyrin (0,012%), -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.


Dos extratos etéreo e etanólico da casca da madeira de Protium paniculatumEngl. foram isolados - e -amirina (0,012%), -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.

ABSTRACT

From the bark of Guarea carinata was isolated as main constituent a diacetilated triterpen (I) of protolimonoids type, derived from apo-tirucalol, that showed antifeedant activity in biological control of Urbanus acawoios(Lepidoptera,Hesperiidae).
