Objective To study the chemical constituents from the bark of Juglans mandshurica. Methods The compounds were isolated and purified by column chromatography on silica gel,HPLC,and recrystallization.Their structures were elucidated by the physicochemical and spectroscopic evidences. Results Fifteen compounds were identified as:4,8-dihydroxynaphthalenyl-O-βD-(6′-acetoxyl)gluco- pyranoside(Ⅰ),dihydrokaempferol(Ⅱ),juglone(Ⅲ),daucosterol(Ⅳ),kaempferol(Ⅴ),4,8-dihy- droxynaphthalenyl-1-O-β-D-[6′-O-(3″,5″-dimethoxy-4″-hydroxybenzoyl)] glucopyranoside(Ⅵ), kaempferol-3-O-α-L-rhamnoside(Ⅶ),3,3′-dimethoxylellagic acid(Ⅷ),naringenin(Ⅸ),quercetin (Ⅹ),reginolone(Ⅺ),quercetin-3-O-α-L-rhamnoside(Ⅻ),naringenin-7-O-β-D-glucoside(ⅩⅢ),4,8- dihydroxynaphthalenyl-1-O-β-glucoside(ⅩⅣ),4,5,8-trihydroxy-α-tetralone-5-O-β-D-[6′-O-(4″-hy- droxy-3″,5″-dimethoxy-benzoyl)] glucoside(ⅩⅤ).Conclusion CompoundⅠ(juglamanol)is a new compound.CompoundsⅡ,Ⅶ—Ⅸ,Ⅻ,andⅩⅢare isolated from plants of Carya Nutt.for the first time.
