title: The elucidation of the structure of thalicoside F, A. minor oleanane glycoside from Thalictrum minus L.
abstract: 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-beta-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D- glucopyranosyl-(1-->4)-alpha-L-arabinopyranosyl]-11 alpha, 12 alpha-epoxyoleanane-28,13 beta-olide}.
