It is found in the bark of Morus species and has been reported to protect human neuronal cells derived from the human neuroblastoma SH-SY5Y cell line. It has a role as a protective agent and a plant metabolite. It is an organic heterotetracyclic compound, a polyphenol, a chromenochromene, an extended flavonoid and a cyclic ketone."}]
