Chemical investigation of the aerial parts of Pterocaulon interruptum DC., Asteraceae, resulted in the isolation of five compounds: one coumarin, sabandinol, two steroids, stigmasterol and 3-O-acetyl taraxasterol and two flavonoids, quercetin (flavonol) and 7-O-prenyl taxifolin (dihydroxyflavonol). The structures of these compounds were established by spectroscopic analysis. This paper deals with the first report of these compounds in Pterocaulon interruptum DC.
