The reinvestigation of the n-BuOH extract of the roots of Clematis argentilucida led to the isolation of four new oleanane-type triterpenoid saponins, 1-4, four known saponins, 5-8, first isolated from the species, together with ten saponins, 9-18, reported in the preceding papers. The structures of saponins 1-8 were elucidated by extensive spectroscopic(More)
Three new triterpenoid saponins, tomentoside A (1), B (2) and C (3), along with four known saponins (4–7) were isolated from the root of Anemone tomentosa. The structures of the new compounds were elucidated as 3-O-β-d-ribopyranosyl-(1→3)-α-l-rhamnopyranosyl-(1→2)-[β-d-glucopyranosyl-(1→4)]-α-l-arabinopyranosyl hederagenin(More)
