Typical COA:

Amentoflavone is a constituent of a number of plants with medicinal properties, including Ginkgo bilobaChamaecyparis obtusa (hinoki), Hypericum perforatum (St. John’s Wort)[1] or Xerophyta plicata.[2]

It is a biflavonoid (bis-apigenin coupled at 8 and 3' positions).
Amentoflavone can interact with many other medications by being a potent inhibitor of CYP3A4 and CYP2C9, which are proteins used for drug metabolism in the body.[3] It is also an inhibitor of human cathepsin B.[1] 
Amentoflavone has demonstrated some antimalarial activity in trials[4] significant affinities towards the delta-1, kappa opioid receptors (as an antagonist)[5] and the allosteric (benzodiazepine) site on the GABAA receptors. (As a negative allosteric modulator) [6]
