Cyclocariosides II and III: two secodammarane triterpenoid saponins from Cyclocarya paliurus.
Two new secodammarane triterpenoid saponins were isolated from the leaves of Cyclocarya paliurus. Based on chemical and spectral analysis they were assigned as (20S)-20-hydroxy-24-O-alpha-L-arabino-pyranosyl-3,4- secodammar-4(28),11,25-trien-3-oic acid, named cyclocarioside II and 25-hydroxy-(20S,24R)-epoxy-12R-O-beta-D- quinovopyranosyl-3,4-secodammar-4(28)-en,3-oic acid, named cyclocarioside III.
