Triterpene saponins fromThalictrum minus. VIII. Structure of thalicoside D

Thalicoside D — a new triterpene glycoside isolated fromThalictrum minus L. (Ranunculaceae) — has the structure of oleanolic acid 3-O-O--L-rhamnopyranosyl-(12)-O--D-glucopyranosyl-(14)--L-arabinopyranoside 28-O-O--D-glucopyranosyl-(16)--D-glucopyranoside]. This structure was established by the use of the results of acid and alkaline hydrolyses, SIMS spectra, and one- and two-dimensional NMR spectroscopy.Deceased.Irkutsk Institute of Organic Chemistry, Siberian Division, Russian Academy of Sciences.
