Antithrombotic phenolic compounds from Glycyrrhiza uralensis

A new coumestan, named glycyrurol, and nine phenolic compounds were isolated from the ethyl acetate extract of the roots and rhizomes of Glycyrrhiza uralensis. Their structures were elucidated based on spectroscopic analysis and literature data, and anticoagulative assay found significant antithrombotic activity of compounds 4, 8 and 10.
