New Cyclomucidoside C from Astragalus mucidus

A new cycloartane-type triterpene glycoside that was called cyclomucidoside C was isolated from the aerial part of the plantAstragalus mucidus Bunge. Its chemical structure was elucidated based on1H and13C NMR spectral data (COSY, HSQC, HMBC). Studies of extracts ofA. mucidus and cyclomucidoside C did not show antibacterial activity against the three strainsEscherichia coli,Staphylococcus aureus, andPseudomonas aeruginosa.
