Objective: To study the chemical constituents of Astragalus mongolica roots. Methods: The compounds were isolated and purified by column chromatography on silica gel and reverse phase Rp-18. The structures of the compounds were identified by their physico-chemical properties and spectral data. Results: 10 known compounds were isolated and identified as 3-O-β-D-xylopyranosyl-25-O-β-D-glucopyranosylcyclovir (1) (3), Scutellarin C (4), 2 ’, 4’-dimethoxy-3’-hydroxy-isoxantane-6-O-β-D- Glucoside (5), calycosin-7-O-β-D-glucopyranoside (6), 6,4’-dimethoxy-3’-hydroxyisoflavone-7-O-β-D - glucoside (7), β-sitosterol (8), β-daucosterol (9), 6-methoxyanthogenin (10). Conclusion: Compounds 1-3, 5-7, 10 were isolated from this plant for the first time.
