摘要：

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-(beta-D-xylopyranosyl)-beta-D-galactopyranosyl]-kaempferol, 3-O-[2-O-(beta-D-xylopyranosyl)-beta-D-galactopyranosyl]-quercetin, trifolin, hyperin, resveratrol-3-O-glucoside, triandrin, by chemical and spectroscopic methods. Their free radical scavenging properties are also described. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
