Özet
Three new cycloartane-type triterpene glycosides were isolated from the roots of Astragalus schottianus Boiss. Their structures were established as 20(R),25-epoxy-3-O-ß-d-xylopyranosyl-24-O-ß-d-glucopyranosyl-3ß, 6?,16ß,24?-tetrahydroxycycloartane (1), 20(R),25-epoxy-3-O- [ß-d-glucopyranosyl(1 › 2)]-ß-d-xylopyranosyl-24-O-ß-d- glucopyranosyl-3ß,6?,16ß,24?-tetrahydroxycycloartane (2), 3-O-ß-d-xylopyranosyl-3ß,6?,16ß,20(S),24(S), 25-hexahydroxycycloartane (3) by the extensive use of 1D and 2D-NMR techniques and mass spectrometry. © 2012 Phytochemical Society of Europe.
