摘要：

Two novel cycloartane-type glycosides (1-2), 16-O-beta -D-glucopyranosyl-20(S),24(R)-5(alpha),9-diepoxy-2 alpha ,3 beta ,16 beta ,25-tetrahydroxy-9,10-seco-cycloarta-1(10),6(7)-diene and 3-O-beta -D-xylopyranosyl-16-O-beta -D-glucopyranosyl-20(S),24(R)-epoxy-3 beta ,16 beta ,25-trithydroxydroxycycloartane, were isolated from the roots of Astragalus prusianus. The 5 alpha ,9-epoxy structural feature in 1 is encountered for the first time. (C) 2001 Elsevier Science Ltd. All rights reserved.
