摘　　要：Two new C-glycosylflavones were isolated from the whole plant of Mimosa pudica, and their structures were determined as 6,7,3＇,4＇-tetrahydroxyl-8-C-[α-L-rhamnopyranosyl-（1 → 2）]-β-D-glucopyranosyl flavone （1）, 5,7,3＇,4＇-tetrahydroxy-8-C[β-D- apiose-（1 → 4）]-β-D-glycopyranosyl flavone （2）. Their structures elucidated by chemical and spectroscopic analysis including IR, MS, 1D and 2D NMR spectra.Two new C-glycosylflavones were isolated from the whole plant of Mimosa pudica, and their structures were determined as 6,7,3＇,4＇-tetrahydroxyl-8-C-[α-L-rhamnopyranosyl-（1 → 2）]-β-D-glucopyranosyl flavone （1）, 5,7,3＇,4＇-tetrahydroxy-8-C[β-D- apiose-（1 → 4）]-β-D-glycopyranosyl flavone （2）.
