    An isoflavan and saponins from Astragalus depressus L.[Reference: WebLink]

    METHODS AND RESULTS:
    In this study, nine known secondary metabolites were isolated from ethyl acetate and n-butanol extracts of Astragalus depressus L. (Fabaceae family), including one isoflavan, namely pendulone (1) and eight saponins, namely cyclogaleginoside A (2), astrasieversianin II (3), astrasieversianin IV (4), Astrasieversianin VII (5), astrasieversianin VI (6), astrasieversianin XIV (7), dehydrosoyasaponin I (8) and soyasaponin I (9).
    CONCLUSIONS:
    The structures of compounds 1-9 were elucidated by using spectroscopic methods, including 1D and 2D NMR, ESI mass spectrometry and comparison with literature data.
