Abstract:In order to find new structural and biologically active compounds, the constituents from the whole plant of Drymaria diandra Bl. (Caryophyllaceae) were investigated and three new flavone glycosides, named drymariatins B (1), C (2), and D (3), were isolated by solvent partition, Si gel, sephadex LH-20, and Rp-18 column chromatography. Using spectroscopic methods, including two-dimensional nuclear magnetic resonance analysis, the structures of these compounds were elucidated as 6-C-(2-deoxy-β-D-fucopyranosyl)-5,7,4‘‘-trihydroxyl-flavone, 6-C-(2-deoxy-β-D-fucopyranosyl)-7-O-(β-D-glucopyranosyl)-5,4‘‘-dihydroxyl-flavone, and 6-C-(3-keto-β-digitoxopyranosyl)-7-O-(β-D-glucopyranosyl)-5,4‘‘-dihydroxyl-flavone.
