DescripciónThis compound belongs to the class of organic compounds known as flavonolignans. These are non-conventional lignans that derived from flavonoids. They are characterized by a p-dioxin ring substituted at one carbon atom by a C3C6 (phenylpropan) group and fused to the B-ring of the 2-phenylchromene moiety.
