摘要
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 C(47)H(74)O(17){3-beta-O[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->4)-alpha-L-arabiopyranosyl]-11 alpha,12 alpha-epoxyoleanane-28,13 beta-olide}.
