Abstract:
Objective To study the chemical constituents from the exocarp of Juglans mandshurica.Methods The compounds were isolated by Diaion HP-20,Sephadex LH-20,MCI CHP-20,and silica gel column chromatography.Their structures were identified by physicochemical properties and spectroscopic analysis.Results Twelve compounds were elucidated as pinostrobin (Ⅰ),quercetin (Ⅱ),quercetin-3-O-?-D-glucoside (Ⅲ),chrysophanol (Ⅳ),gallic acid (Ⅴ),4-hydroxyl-cinnamic acid methyl ester (Ⅵ),vanillin (Ⅶ),caffeic acid (Ⅷ),4-hydroxylcinnamic acid (Ⅸ),?-sitosterol (Ⅹ),daucosterol (Ⅺ),and 5-hydroxyl-1,4-naphthoquinone (ⅩⅡ).Conclusion The compounds Ⅰ,Ⅳ,and Ⅵ—Ⅸ are isolated from J.mandshurica for the first time.
