A new gallic acid fructose ester from Saxifraga stellaris
Phytochemistry 50(1) (1999)
151-154
Seven compounds have been isolated from methanol extracts of whole Saxifraga stellaris (Saxifragaceae) plants. They were identified as the new compound, 6-O-galloyl fructose, together with 3-O-[2-O-(β-D-xylopyranosyl)-β-D-galactopyranosyl]-kaempferol, 3-O-[2-O-(β-D-xylopyranosyl)-β-D-galactopyranosyl]-quercetin, trifolin, hyperin, resveratrol-3-O-glucoside, triandrin, by chemical and spectroscopic methods. Their free radical scavenging properties are also described.
