| Abstract: | The new cycloartane glycoside cyclogaleginoside E, 20S,24R-cycloartan-3 ,6 ,16,25-tetraol-3-O--D-xylopyranoside-25-O--D-glucopyranoside, was isolated from stems of Astragalus galegiformis L. Its structure was established using enzymatic and total acid hydrolysis, mass spectrometry, and PMR and 13C NMR. |
