Abstract

The herb low cudweed has yielded for the first time a new acylated flavone glycoside, for which the structure of 3′,4′,5,7-tetrahydroxy-6-methoxyflavone 7-O-(6″-O-caffeyl-β-D-glucopyranoside) has been established. In addition, 6-methoxyluteolin, 6-hydroxyluteolin 7-O-β-D-glucopyranoside, and scutellarein 7-O-β-D-glucopyranoside have been isolated. Identification was made on the basis of UV, IR, PMR, and mass spectra, the products of alkaline and acid hydrolyses, and the results of elementary analyses, melting points, and specific rotations.
