J Asian Nat Prod Res. 2006 Jan-Mar;8(1-2):93-8. doi: 10.1080/10286020500480217.

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 (3beta,12beta)-25-hydroxyl-12-O-beta-D-quinovopyranosyl-3-O-beta-D-quinovopyranoside (1), and (20S,24R)-epoxydammarane (3beta, 12beta)-25-hydroxyl-12-O-alpha-L-arabinopyranosyl-3-O-(5'-O-acetyl)-alpha-L-arabinofuranoside (2).
