The phytochemical study of plant S．strangulata has not beenreported so far．In the course of our searching for biologically active substances from thisplant，two new flavone glucosides（1，2）were isolated．The present paper covers the isolationand structural elucidation of the two new compounds．展开更多
From the alcoholic extract of the whole plants of Serratula strangulata, two new compounds, named strangusin-A (1) and strangusin-B (2) have been isolated and their structures were established by spectroscopic method.
