Rg. Shu et al., CYCLOCARIOSIDES-II AND CYCLOCARIOSIDES-III - 2 SECODAMMARANE TRITERPENOID SAPONINS FROM CYCLOCARYA-PALIURUS, Planta medica, 61(6), 1995, pp. 551-553
Two new secodammarane triterpenoid saponins were isolated from the lea
ves of Cyclocarya paliurus. Based on chemical and spectral analysis th
ey were assigned as (20S)-20-hydroxy-24-O-alpha-L-arabinopyranosyl 3,4
-secodammar-4(28),11,25-trien-3-oic acid, named cyclocarioside II and
25-hydroxy-(20S, a-D-quinovopyranosyl-3,4-secodammar-4(28)-en,3-oic ac
id, named cyclocarioside III.
