Thirteen compounds have been isolated from the methanol extract of Saxifraga cuneifolia L. (Saxifragaceae) whole plant. These were identified as five new compounds, (E)-5-O-ß-D-glucopyranosyl-stilbene-3,3', 4,5'-tetraol, (E)-4-O-ß-D-glucopyranosyl-5-methoxy-stilbene-3,3',5'-triol, 4-[4'-O-(6''-O-galloyl-ß-D-glucopyranosyl)-3'-hydroxyphenyl]butan-2-one, 3-O-(6''-O-galloyl-ß-D-glucopyranosyl)-epigallocatechin and 3-O-ß-D-glucopyranosyl-epigallocatechin, together with the known compounds 4-[4'-O-ß-D-glucopyranosyl-3'-hydroxyphenyl]-butan-2-one, (R)-rhododendrin, 1-O-galloyl-ß-D-glucose, catechin, 3-O-galloyl-epigallocatechin, gallocatechin, clitorin and rutin, by chemical and spectroscopic methods. Their free radical scavenging properties are also described.
