Identification and quantification of flavonoids from Chuquiraga spinosa (Asteraceae).
Nine flavonol glycosides (quercetin-3-O-glucuronide, quercetin-3-O-rutinoside, quercetin-3-O-glucoside, kaemperol-3-O-glucuronide, kaemperol-3-O-rutinoside, kaempherol-3-O-glucoside, isorhamnetin-3-O-glucuronide, isorhamnetin-3-O-rutinoside and isorhamnetin-3-O-glucoside) were isolated from the aerial parts of Chuquiraga spinosa (R. et P.) D. Don (Asteraceae). The identification of the compounds was carried out by HPLC/DAD, HPLC/MS and NMR analysis. These compounds may be useful in the chemotaxonomy of the genus and species.
