Natural products from Scorzonera aristata (Asteraceae).
The aerial parts of Scorzonera aristata Ramond ex DC., collected in the South Tyrolean Dolomites, yielded the flavonoids quercetin 3-O-glucoside, rutin, and isoorientin, and the caffeic acid derivatives chlorogenic acid, 4,5-dicaffeoyl quinic acid, and 3,5-dicaffeoyl quinic acid. Sub-aerial parts contained caffeic acid methyl ester, 3,5-dicaffeoyl quinic acid, and the triterpenes 3alpha-hydroxyolean-5-ene, lupeol, and magnificol. Chemosystematic implications of the isolated compounds are discussed briefly.
