Abstract

Two new C-glycosylflavones, apigenin 7,4′-dimethyl ether 6- C- β-[(4″′-acetyl-L-rhamnopyranosyl)-(1→2)-xylopyranoside] (1) and apigenin 7,4′-dimethyl ether 6- C- β-L-rhamnopyranosyl-(1→2)-xylopyranoside (2) were isolated from the leaves of Iris gracilipes (Iridaceae), along with two known flavonoids, swertiajaponin (3) and swertisin (4). C-Xylosylflavones 1 and 2 were elucidated by UV and NMR spectroscopy, mass spectrometry, and acid and alkaline hydrolyses. These novel compounds were also presented in the flowers.
