Abstract
Four new phenolic glycosides, beta -apiofuranosyl-(1 -->2)-beta -glueopyran osides (1-4), along with the cycloartane triterpenes 20(R),25-epoxy-3 beta ,6 alpha ,16 beta ,24 alpha -tetrahydroxycycloartane (5) and 20(R),24(S)-ep oxy-3 beta ,6 alpha ,25-trihydroxycycloartan-16-one (6) were isolated from roots of Astragalus zahlbruckneri. The structure elucidation of all compoun ds was based on their H-1 and C-13 NMR spectral data including 1D-TOCSY, DQ F-COSY, HSQC, and HMBC experiments.
