title: Two flavone C-glycosides from the style of Zea mays 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.
