  • Purification of isolated compounds using chromatographic techniques.
  • Structure elucidation of the purified compounds utilizing comprehensive spectroscopic analyses (e.g., NMR, MS).

    • Main Results:

    • Ten coumestan compounds were successfully isolated from the plant roots.
    • Eight of the isolated coumestans were identified as new chemical entities, designated hedysarimcoumestans A-H.
    • Two known coumestans, 1,3,9-trimethoxycoumestan and aureol, were also identified.

    Conclusions:

    • The roots of Hedysarum multijugum are a rich source of diverse coumestan compounds.
    • The discovery of novel hedysarimcoumestans expands the known repertoire of coumestan natural products.
    • These findings provide a basis for further investigation into the biological activities and potential applications of these isolated coumestans.
