  Triterpene Glycosides from Tragacantha stipulosa and Their Genins. Structure of Cyclostipuloside E

  摘要：

  The known compound trojanoside A (1) and a new cycloartane glycoside cyclostipuloside E (2) were isolated from the aerial parts of Tragacantha stipulosa Bofiss. The structure of cyclostipuloside E was proposed as 24R-cycloartan-3beta,6alpha,16beta,24,25-pentaol 6,16,25-tri-O-beta-D-glucopyranoside 3-O-beta-D-xylopyranoside based on physicochemical data and chemical transformations.

  The aerial part of Astragalus mucidus Bunge (Leguminosae) contains several isoprenoid compounds, two of which were isolated pure. The structure of a new triterpene glycoside of the cycloartane series, cycloascidoside A, was determined as 24R-cycloartan-3β,6α,16β,24,25-pentaol-3-O-β-D-xylopyranoside-6-O-β-Dglucopyranoside. D-3-O-Methyl-chiro-inositol was also identified.

  Two known compounds of the cycloartane series - cyclosieversiosides C and G - and the new glycoside cycloglobiceposide B - 24R-cycloartane-3 beta,6 alpha,16 beta,24,25-pentaol 16,25-di-O-beta-D-glucopyranoside 3-O-beta-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 H-1 and C-13 NMR spectra.
