A flavonoid glycoside was isolated from Anthocepharus chinensis. Its structure was elucidated by spectral data and determined to be myricetin 3-O-(4"-acetyl)-alpha-fucoside. This flavonoid glycoside and its aglycone showed potent inhibition against rat and porcine lens aldose reductase. The flavonoid aglycone also inhibited sorbitol accumulation in human red blood cells.
