Two new acylated C-glycosylflavones were isolated from the leaves of Iris lactea var. chinensis, and their structures were elucidated on the basis of extensive NMR experiments and mass spectrometry methods and were assigned as 5-hydroxy-4'-methoxyflavone-7-O-(beta-D-2 '''',4 ''''-diacetylrhamnopyranosyl)-6-C-[O-(alpha-L-6'-acetyl-glucopyranosyl)-1 -> 2-beta-D-glucopyranoside] (irislactin A) and 5-hydroxy-4',7-dimethoxyflavone-6-C-[O-(alpha-L-2',3'-diacetylrhamno-pyranosyl)-1 -> 2-beta-D-glucopyranoside] (irislactin B).
