Popis: A new acylated flavone glycoside has been isolated for the first time from the herb marsh cudweed, and for it the structure of 6″-caffeyl-7-β-D-glucopyranosyloxy-4′,5-dihydroxy-3′,6′dimethoxyflavone has been established. In addition, the aglycone, identified as 4′,5,7-trihydroxy-3′,6-dimethoxyflavone has been isolated. The identifications were made on the basis of UV, IR, PMR, and mass spectra, the products of alkaline and acid hydrolyses, and the results of elementary analysis, melting points, and specific rotations.
