By means of enzymatic degradation and by application of a selective cleavage method for the glucuronide linkage, as well as by the carbon-13 nuclear magnetic resonance (^<13>C-NMR) analysis, the structures of two astragalosides, which were isolated as two of eleven astragalosidesfrom Astragali Radix (the root of Korean Astragalus membranaceus, Leguminosae), were elucidated : astragaloside VII is 3-O-β-D-xylopyranosyl-6-O-β-D-glucopyranosyl-25-O-β-D-glucopyranosyl-cycloastragenol (4) and astragaloside VIII is 3-O-[α-L-rhamnopyranosyl (1→2)-β-D-xylopyranosyl (1→2)-β-D-glucuronopyranosyl] soyasap-ogenl B (8). Astragaloside VII (4) is an unprecedented example of a triterpene-tridesmoside.
