Study on the constituents of Astragali Semen, the seeds of Astragalus complanatus R. BR. (Leguminosae), led to the identification of nine known flavonoids (1, 4, 6-12) and characterization of three new flavonol glycosides (2, 3, 5) as rhamnocitrin 3-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside, 3-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranosyl rhamnocitrin 4'-O-β-D-glucopyranoside and 3-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranosyl kaempferol 4'-O-β-D-glucopyranoside, respectively. The occurrence of methyl dihydrophaseate (13), roseoside (14), blumenol C glucoside (15), (±)-3-oxo-α-ionyl glucoside (16a, 16b), tuberonic acid glucoside (17), benzylalcohol-O-α-L-arabiopyranosyl(1→6)β-D-glucopyranoside (18), piceid (19) and deoxyrhaponticin (20) were also disclosed.
