Isolated from the roots of Dorstenia psilurus, it exhibits alpha-glucosidase inhibitory activity. It has a role as a metabolite and an EC 3.2.1.20 (alpha-glucosidase) inhibitor. It is a 7-hydroxyflavonol, an organic heterotricyclic compound, an extended flavonoid, a trihydroxyflavone and a pyranochromane."}]
