Article abstract of DOI:10.1016/0031-9422(83)80172-1

A new polyoxigenated chromone-C-glucoside, named biflorin, was isolated from the roots of Pancratium biflorum collected at flowering time.The structure of the compound was established as 5,7-dihydroxy-2-methylchromone-C₆-β-D-glucopyranoside on the basis of comprehensive spectral analysis (UV, IR, 1H NMR, MS, <α>_D) and crucial chemical transformations of the compound and its derivatives.The biochemical significance of the occurence and ontogenic variations of biflorin and other polyoxygenated chromones in the title species is discussed.Key Word Index - Pancratium biflorum; Amaryllidaceae; roots; chromone-C-glucoside; biflorin; 5,7-dihydroxy-2-methylchromone-C₆-β-D-glucopyranoside; chromone-metal ion complex; phosphodiesterase inhibitor.
