| Abstract: | From the terrestrial part ofThalictrum minus L. (Ranunculaceae) a novel triterpenoid diglycoside was isolated. The genin of this glycoside is a new cycloartane triterpenoid.
The structure of the glycoside was established on the basis of 1D and 2D NMR spectroscopy and FAB mass spectrometry as 22S,25-epoxy-3-O-β-d-galactopyranosyl-29-O-β-d-glucopyranosyl-9β, 19-cyclo-20S-lanostane-3β,16β,24S,29-tetrol.
For Part 10 see Ref. 1.
