Two Flavone <i>C</i>-Glycosides from the Style of <i>Zea </i><i>m</i><i>ays</i> with Glycation Inhibitory Activity

Abstract

A new flavone C-glycoside, chrysoeriol 6-C-beta-boivinopyranosyl-7-O-beta-glucopyranoside (1), and a known flavone C-glycoside (2) were isolated from the style of Zea mays. Each compound contains the rare sugar boivinose. These flavones exhibited glycation inhibitory activity similar to that of aminoguanidine, a known glycation inhibitor.
