“…These data suggested the presence of triterpenes esterified with fatty acids. In order to identify the fatty acids, M2 was submitted to transesterification reaction with MeONa/ MeOH (Mendes et al, 1999). After the usual work-up was obtained one fraction containing the sesquiterpene alcohols and another containing the fatty acid methyl esters.…”

“…7 A investigação química de outras espécies de Byrsonima relata o isolamento de esteroides, triterpenos, flavonoides e proantocianidinas. 7,[13][14][15][16] Os radicais livres, na forma de espécies reativas de oxigênio (EROs) e espécies reativas de nitrogênio (ERNs), são uma parte integrante da fisiologia normal. 17 No entanto, as EROs exercem um papel importante nos processos degenerativos ou patológicos em várias doenças humanas, como o envelhecimento, 18 câncer, doenças coronarianas, doença de Alzheimer, 19 desordens neurodegenerativas, aterosclerose e inflamação.…”

“…Although the triterpene moiety 3β, 11β-dihydroxy-olean-12-ene (3) has been obtained through synthesis 10,11 this is the first report of its isolation from a natural source. A significant number of plant species in different families contain fatty acids esterified with triterpenes or steroids, usually as a mixture of fatty acids, 12,13 however, previous studies of Erythroxylum also showed only palmitates. 4 …”
