AIM To study the chemical constituents of Astragalus hoantchy Franch. METHODS We isolated and elucidated the chemical constituents using chromatography and spectral evidences, respectively. RESULTS and CONCLUSION Three isoflavans and one isoflavone have been isolated and identified. Among them, compound 3 is a new compound,and identified as 2′,4′ dimethoxy 3′ hydroxy isoflavan 6 O β glucopyranoside; compound 1 and 4 were isolated from the Genus astragalus for the first time.
