Two new cycloartane saponins from the roots of Astragalus membranaceus.
Two new cycloartane-type triterpenoid saponins were isolated from the roots of Astragalus membranaceus (FISCH.) BGE. (Leguminosae) cultivated in Kangwon province, Korea. These saponins were named astramembranosides A and B and were established to be cycloastragenol 6,25-di-O-beta-D-glucopyranoside (astramembranoside A) and cyclocanthogenin 3-O-beta-D-glucopyranosyl(1-->2)-beta-D-xylopyranoside ...
متن کاملEffects of cycloartane saponins from hairy roots of Astragalus membranaceus Bge., on human tumor cell targets.
For the first time three different natural compounds, isolated from hairy roots of Astragalus membranaceus, cultivated in airlift bioreactor were tested for their cytotoxic potential and apoptosis induction in a panel of human tumor cell lines. Root cultures, cultivated in bioreactor gave 18.5 g l(-1) dry wt roots with the highest astragaloside production in vitro up to now - 1.64% (astragalosi...

A new cycloartane-type triterpene glycoside, agroastragaloside V (1) was isolated from the roots of Astragalus membranaceus. The structure was identified as 3-O-β-(2'-O-acetyl)-D-xylopyranosyl-6-O-β-D-glucopyranosyl-(24S)-3β,6α,24α,25-tetrahydroxy- 9,19-cyclolanostane, by means of spectroscopic methods, including HR-FAB/MS, 1D NMR (1H, 13C, DEPT), 2D NMR (gCOSY, gHSQC, gHMBC, NOESY), and IR spe...
