摘　　要：A new C-glycosylflavone,5-hydroxyl-4′,7-dimethoxyflavone-6-C-[0-(α-L-3″-acetylrhamno-pyranosy)-1→2-β-D-glucopyranoside](1),along with five known C-glycosylflavones,5-hydroxy-4′,7-dimethoxyfavone-6-C-[0-(α-L-2′″-acetylrhamnopyranosy1)-1→2-β-D-glucopyranoside](2),embinin(3),embigenin(4),swertisin(5)and swertiajaponin(6)were isolated from the leaves of Iris tectorum Maxim.Their structures were elucidated on the basis of extensive NM R experiments and spectral methods and their cytotoxic activities against A 549(lung cancer)human cell lines were determined.
