Bioactive Pentacyclic Triterpenes from the Stems of Combretum laxum

Abstract: Two new triterpene glucosides, β-d-glucopyranosyl 2α,3β,24-trihydroxyolean-12-en-28-oate and β-d-glucopyranosyl 2α,3β,23,24-tetrahydroxyurs-12-en-28-oate, in addition to nine known compounds belonging to three different triterpene classes (oleanane-, ursane- and lupane-type) have been isolated from the stems of a specimen of Combretum laxum growing in the “Pantanal” of the central-western region of Brazil. Among the known triterpenes, β-d-glucopyranosyl 2α,3β,6β-trihydroxyolean-12-en-28-oate is reported for th… Show more

“…As espécies da família Fabaceae exercem importante contribuição na fixação de nitrogênio no solo quando em associação com bactérias do gênero Rhizobium [27]. Já espécies da família Combretaceae possui imenso valor medicinal [28]. A família Myrtaceae apresenta grande potencial econômico, muitas de suas espécies são utilizadas na alimentação [29].…”

“…The mixture was then subjected to further purification yielding three pure known triterpene acids: oleanolic ( 1 ), masilinic ( 2 ), and arjunolic ( 3 ) with their corresponding antimigratory IC 50 at 14.0, 9.0, and >40.0 μ m , respectively. The compounds were identified based on their spectroscopic analysis and comparing with literature .…”

“…Triterpenes that were isolated from the genus Combretum also showed activities against another microorganisms, like fungi (BISOLI et al, 2008), bacteria (ANGEH et al, 2007a;ANGEH et al, 2007b;SONGCA, RAMURAFHI;OLUWAFEMI, 2013), viruses (ASRES;BUCAR, 2005) and other species of parasites (TELES et al, 2011;HAAVIKO et al, 2014).…”
