Popis: Three novel compounds, as well as a bitter-tasting flavonoid glycoside of known structure, kaempferol-3-O-β- d -glucopyranoside-7-O-α- l -rhamnopyranoside, were isolated from the rhizomes of Selliguea feei. The structures of the new compounds were determined as (−)-4β-carboxymethyl epiafzelechin (3′-deoxydryopteric acid), epiafzelechin-(4β→8, 2β→O→7)-epiafzelechin-(4β→8)-3′-deoxydryopteric acid methyl ester (selligueain B), and (+)-afzelechin-O-β- 4′- d -glucopyranoside.
