Pentacyclic triterpenes and other constituents from Ficus cordata (Moraceae)

Abstract

Two new pentacyclic triterpenes 8,26-cyclo-urs-21-en-3β,20β-diol (1) and 3β-acetoxy-8,26-cyclo-ursan-20β-ol (2) together with 3-friedelanone, oleanolic acid, betulinic acid, lupeol acetate, α- and β-amyrine, 3,5,7,4′-tetrahydroxyflavane, and 3,5,7,3′,4′- pentahydroxyflavane were isolated from the stem bark of Ficus cordata (Moraceae). The structures of these secondary metabolites were established using 1D and 2D NMR spectra and by comparison with published data or with authentic samples. Compounds 1 and 2 exhibited weak antibacterial and no antifungal activity. © 2008 Verlag der Zeitschrift für Naturforschung.
