New lupane glycosides from Pulsatilla chinensis

Planta Med. 2002 Feb;68(2):183-6. doi: 10.1055/s-2002-20254.

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.
