ABSTRACT

From the ethanol extract of Adina rubella;twelve compounds were isolated by silica gel and ODS col-umn chromatography.Their structures were identified by spectroscopic analysis as5;7-dihydroxy-2-methyl-chromone-7-O-β-D-glucopyranoside(1);scopolin(2);(+)-lyoniresinol-3a-O-β-D-glucopyranoside(3);(6S;7R;8R)-7a-[(β-D-glucopyranosyl)oxy]lyoniresinol(4);harman-3-carboxylic acid(5);lyaloside(6);3-oxoquinovid acid(7);oleanolic acid(8);3-acetyl oleanolic acid(9);quinovic acid 3-O-β-D-glucopyranosyl-28-O-β-L-rham-nopyranosyl ester(10);quinovic acid 3-O-β-D-glucopyranosiyl-28-O-β-D-glucopyranosyl ester(11)and pyrocin-cholic acid 3-O-α-L-rhamnopyranosyl-28-[β-D-glucopyranosyl-(1 →6)-O-β-D-glucopyranosyl]ester(12). Compounds 3;4;6;8-10 were isolated from this plant for the first time.
