Abstract: AIM To study the chemical constituents from the leaves of Cyclocarya paliurus (Batal.) lljinskaja.METHODS The ethyl acetate fraction of methanol extract from C.paliurus leaves was isolated and purified by silica,ODS and semi-preparative HPLC,then the structures of obtained compounds were identified by spectral data.RESULTS Eleven compounds were isolated and identified as (6S,7R,8R)-7α-[(β-glucopyranosyl) oxy] lyoniresinol (1),lyoniside (2),(-)-lyoniresinol 3 α-O-β-D-xylopyranoside (3),dihydrodehydrodiconiferyl alcohol 4'-O-β-D-glucoside (4),kaempferol-3-O-α-L-rhamnoside (5),kaempferol-3-O-α-L-(4"-Z-p-cumaroyl)-rhamnoside (6),naringenin (7),4'-hydroxywogonin (8),1-(3',4'-dihydroxyphenyl)-7-(4"-hydroxyphenyl)-4-hepten-3-one (9),grasshopper ketone (10),p-hydroxybenzoic acid (11).CONCLUSION Except for compounds 5,11,all the compounds are isolated from this plant for the first time.
