ABSTRACT

The aroma of Licania tomentosa was obtained by hydrodistillation and extraction with pentane and their volatiles constituents were identified by gas chromatography - mass spectrometry (GC/MS). The main components identified were 1-hexanol (11.1%), 4-heptanol (10.5%), 3-methylbutyl butanoate (7.4%), hexanal (7.1%) and myrcene (6.4%).


O aroma dos frutos de Licania tomentosa foi obtido por hidrodestilação e extração com pentano, e seus constituintes voláteis identificados através de cromatografia de gás acoplada à espectrometria de massas (CG/EM). Os principais componentes identificados foram l-hexanol (11,1%), 4-heptanol (10,5%), butanoato de 3-metilbutila (7,4%), hexanal (7,1%) e mirceno (6,4%).

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

Coumestrol and -amyrin were isolated from the woody liane of a Derris species, collected at the Estrada do Xapurí (Acre). The presence of two coumestrol derivatives was postulated on the basis of mass spectral analyses.


Do cipó de uma espécie de Derris, coletado na Estrada do Xapurí (Acre), foram isolados comestral e a-amirina . A presença de dois derivados do cumestrol foi postulada com base na análise de espectros de massas.
