Secondary Metabolites from Hedysarum setigerum

摘要

We previously reported the isolation of five flavonoids from the aerial part of Hedysarum setigerum. These included isorhamrietin, avicularin, roifolin, linarin, and diosmin [1]. In continuation of the study of secondary metabolites of H. setigerum to find antiviral agents, we isolated another six flavonoids and four sterols.
