Triterpenóides pentacíclicos das folhas de Terminalia brasiliensis

Abstract

Eleven oleanane, ursane and lupane-type triterpenes were isolated from the leaves of Terminalia brasiliensis Camb, daturadiol (3β,6β-dihydroxy- olean-12-ene), 3β-hydroxy-30-norlupan-20-one, lupenone, β-amyrenone, α-amyrenone, lupeol, β-amyrin, α-amyrin, betulin, erythrodiol and uvaol, in addition to squalene, sitosterol and α-tocopherol. The structures of these compounds were identified by 1H and 13C NMR spectral analysis and comparison with literature data.
