A Phenol Glucoside, Uncommon Coumarins and Flavonoids from Pelargonium sidoides DC

Structural examination of the metabolic pool of the aerial parts of Pelargonium sidoides DC has led to the isolation of two new metabolites, 4-allyl-2,5-dimethoxyphenol-1-β -D-glucopyranoside and 6,7-dihydroxycoumarin-8-sulfate, along with a series of uncommon compounds including (2R,3R)-(+)-dihydroquercetin-3-β -glucopyranoside, (2R,3R)-(+)-dihydrokaempferol-3-β - glucopyranoside, fraxetin-7-β -glucopyranoside, 7-methoxycoumarin-6-β...
