A new flavonoid glycosides, 5,7-dihydroxy-4'-methoxyflavone-7-O-[6-O-(4-O-acetyl-α-L-rhamnosyl)-3-O-β-D-glucosyl]-6-O-acetyl-β-D-glucoside and three known flavonoid glycosides, 5,7-dihydroxy-4'-methoxyflavone-7-O-[6-O-(4-O-acetyl-α-L-rhamnosyl)]-β-D-glucoside, 3,5,7,4'-tetrahydroxyflavonol-3-O-β-D-glucoside and 5,7-dihydroxy-4'-methoxyflavone-7-O-(6-O-α-L-rhamnosyl)-β-D-glucoside were isolated from the whole plant of Thalictrum przewalskii. Their structures were determined on the basis of spectroscopic evidences.
