Abstract
Two new dammarane triterpenoid glycosides named cyclocarosides B (1) and C (2) were isolated from the leaves of Cyclocarya paliurus. Based on FAB-MS, HRESI-MS, IR, 1H NMR, 13C NMR, and 2D-NMR (HMQC, HMBC, COSY, ROESY) data, the structures of cyclocarosides B (1) and C (2) were elucidated as (20S,24R)-epoxydammarane (3β,12β)-25-hydroxyl-12-O-β-d-quinovopyranosyl-3-O-β-d-quinovopyranoside (1), and (20S,24R)-epoxydammarane (3β, 12β)-25-hydroxyl-12-O-α-l-arabinopyranosyl-3-O-(5′-O-acetyl)-α-l-arabinofuranoside (2).Keywords
