A new triterpenoid saponin, thalicoside F was isolated from the above- ground part of Thalictrum minus L. (Ranunculaceae family) collected in Eastern Siberia (Russia). The structure of thalicoside F was elucidated by a combination of 1D- and 2D-NMR spectroscopy and mass spectroscopy, and was determined to be C47H74O17{3-β-O-[α-L-rhamnopyranosyl-(1 → 2)-β- D-glucopyranosyl-(1 → 4)-α-L-arabinopyranosyl]-11α, 12α-epoxyoleanane- 28,13β-olide}.
