Abstract

Two new flavone glucosides that are considered to be useful chemotaxonomic markers were isolated from the leaves of Pyrus serotina cv. Nijisseiki. Spectral and chemical data enabled their structures to be established as 7, 4'-dihydroxy-5, 3'-dimethoxyflavone 7-O-β-D-glucoside and 7, 4'-dihydroxy-5, 3'-dimethoxy-flavone 4'-O-β-D-glucoside.
