Triterpenes and other Metabolites from Tibouchina urvilleana

Abstract

The chemical study of the leaves and stems of Tibouchina urvilleana afforded triterpenes of different types: four oleanane, four ursane, one glutinane, and one taraxerane. Also, two flavonoids and two sterols were isolated. Additionally, the toxicity and topical antiinflammation activity of the extracts were tested.
