Effects of the Loach Polysaccharide on Removal of Reactive Oxygen Species and Protection of DNA Chains.

The effects of the Misgurnus anguillicaudatus polysaccharide on removal of reactive oxygen species in some modified chemical systems were investigated by chemiluminescence and spectrophotometry. The inhibition of the damage of DNA chain induced by hydroxyl radical by the Misgurnus anguillicaudatus polysaccharide was observed by chemiluminescence. The results showed that the Misgurnus anguillicaudatus polysaccharide could efficiently remove O.(-)(2),.OH, H(2)O(2) and other active compounds of oxygen and significantly protected DNA chains from being damaged by free radicals.

Two new triterpenoid glycosides from Cyclocarya paliurus.

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).
