Patensin, a new triterpenoid glycoside, was isolated from the ethanolic extraction of the roots of Pulsatilla patens var. multifida. Its structure was established as hederagenin 3-O-beta-D-galactopyranosyl-(1-->2)-beta-D- glucopyranoside on the basis of hydrolysis and spectral evidence including 1D and 2D NMR techniques.
