ABSTRACT
A total of twelve compounds were isolated from the ethyl acetate of the water extract of honey-fried Eriobotrya japonica through column chromatography over silica gel,Sephadex LH-20,RP-18,and preparative HPLC. Their structures were established by MS,1 D NMR and 2 D NMR data as japonicanoside A( 1),nerolidol-3-O-α-L-rhamnopyranosyl-( 1â2)-ß-D-glucopyranoside( 2),nerolidol-3-O-α-L-rhamnopyranosyl-( lâ4)-α-L-rhamnopyranosyl-( 1 â 2)-[α-L-( 4-trans-feruloyl)-rhamnopyranosyl-( 1 â 6) ]-ß-D-glucopyranoside( 3),( +)-catechin( 4),(-)-epicatechin( 5),kaempferol 3-O-α-L-rhamnopyranoside( 6),quercitrin( 7),quercetin-3-O-ß-D-galactopyranoside( 8),quercetin-3-O-ß-glucopyranoside( 9),vanillin( 10),protocatechuic aldehyde( 11),and maltol( 12). Among them,1 is a new phenolic glycoside.
