Amentoflavone


Amentoflavone is a biflavonoid (bis-apigenin coupled at 8 and 3' positions, or 3′,8′′-Biapigenin) constituent of a number of plants including Ginkgo biloba, Chamaecyparis obtusa (hinoki), Hypericum perforatum (St. John’s Wort) and Xerophyta plicata.
Amentoflavone can interact with many medications by being a potent inhibitor of CYP3A4 and CYP2C9, which are enzymes responsible for the metabolism of some drugs in the body. It is also an inhibitor of human cathepsin B.
