Structure of cycloglobiseposide C from Astragalus globiceps
Khimiia Prirodnykh Soedineniĭ = Chemistry of Natural Compounds [Russian] 35(6) (1999)
650-652
A new cycloartane glycoside, cycloglobiseposide C, is isolated from the roots of Astragalus globiceps Bunge. The structure 3-O-β-D-glucopyranosyl-(1-3)-O-α-L-arabinopyranosyl cycloglobisepogenin is proposed on the basis of NMR spectra.

The structure of cycloglobiceposide B from Astragalus globiceps
Khimiia Prirodnykh Soedineniĭ = Chemistry of Natural Compounds [Russian] 35(2) (1999)
192-195
Two known compounds of the cycloartane series - cyclosieversiosides C and G - and the new glycoside cycloglobiceposide B - 24R-cycloartane-3β,6α,16β,24,25-pentaol 16,25-di-O-β-D-glucopyranoside 3-O-β-D-xylopyranoside - have been isolated from the roots of Astragalus globiceps Bunge. The structures of the glycosides were established on the basis of the the results of enzymatic and total hydrolysis and also of 1H and 13C NMR spectra.
