A new flavone O-glycoside and other constituents from wheat leaves (Triticum aestivum L.).

From leaves of Triticum aestivum a new O-glycosylflavone has been isolated together with chlorogenic acid and its 3'-methyl ether and 6 C-glycosylflavones. The structure of the new flavonoid was determined by 1D and 2D NMR techniques and other spectral evidence as 5,7-dihydroxy-3',4',5'-trimethoxyflavone-7-O-beta-rutinoside.
