A new lupane type triterpenic acid, pulsatillic acid, and two new lupane type triterpenoid glycosides, pulsatilloside A and B, along with the known 23-hydroxybetulinic acid were isolated from the roots of Pulsatilla chinensis. Their structures were characterized as 3-oxo-23-hydroxy-lup-20(29)-en-28-oic acid, 3β, 23-dihydroxy-lup-20(29)-en-28-oic acid 3-O-α-l-arabinopyranoside and 3β, 23-dihydroxy-lup-20(29)-en-28-oic...
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-β-d-galactopyranosyl-(1 → 2)-β-d-glucopyranoside on the basis of hydrolysis and spectral evidence including 1D and 2D NMR techniques.
