  • Title: New lupane glycosides from Pulsatilla chinensis.
    Author: Ye W, Zhang Q, Hsiao WW, Zhao S, Che CT.
    Journal: Planta Med; 2002 Feb; 68(2):183-6. PubMed ID: 11859478.
    Abstract:
    Two new lupane glycosides along with five known triterpenoids were isolated from the roots of Pulsatilla chinensis (Ranunculaceae). The structures of the new glycosides were determined to be 3-O-beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl-23-hydroxybetulinic acid 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (pulsatilloside D, 6) and 3-O-[beta-D-glucopyranosyl(1-->4)][alpha-L-rhamnopyranosyl(1-->2)]-alpha-L-arabinopyranosyl-23-hydroxybetulinic acid 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (pulsatilloside E, 7) by spectroscopic analysis and chemical methods. The compounds were evaluated for cytotoxic activities against K-562 human leukemia and HeLa cells.
