Abstract
This project is to investigate chemical compositions from the roots of Erythrina corallodendron. Through the methods of silica gel,ODS,Sephadex LH-20 column chromatography and preparative HPLC,15 compounds were isolated from the 95% ethanol extract of the roots of E. corallodendron. Based on spectroscopic techniques,the structures of these compounds were identified as 10,11-dioxoerythraline( 1),erythrinine( 2),erythraline( 3),11-methoxyerythraline( 4),cristanines B( 5),erythratine( 6),erysotrine( 7),medioresinol( 8),( ±)-ficusesquilignan A( 9),( +)-pinoresinol( 10),nicotinic acid( 11),dibutyl phthalate( 12),vanillic acid( 13),3-hydroxy-1-( 4-hydroxy-3-methoxyphenyl)-1-propanone( 14),and syringic acid( 15). Compounds 8-10 are isolated from genus Erythrina for the first time and all compounds are isolated from E. corallodendron for the first time. Furthermore,this paper screened the antioxidant and cytotoxic activities of the compounds using models of liver microsomal oxidation inhibition and MTT.
