TWO FLAVONOL GLYCOSIDES FROM CHENOPODIUM AMBROSIOIDES

Abstract Two new flavonol glycosides, kaempferol 3-rhamnoside-4′-xyloside and kaempferol 3-rhamnoside-7-xyloside along with kaempferol, isorhamnetin and quercetin have been identified from the fruits of Chenopodium ambrosioides . Their structures were established using spectroscopic and chemical evidence.
