Definition:An extended flavonoid that is 3,4,6a,11b-tetrahydro-2H,6H-[1]benzofuro[3,2-b]pyrano[3,2-g]chromene substituted by hydroxy groups at positions 3, 5, 6a and 9, geminal methyl groups at positions 2, an oxo group at position 6 and a prenyl group at position 11b. It has been isolated from the twigs of Morus nigra.
