3,5,3'-Trihy-droxy-4'-meth-oxy-7-(3-methyl-but-2-en-yloxy)flavone.


ABSTRACT: The title compound pteleifolosin C, C(21)H(20)O(7), was isolated from the petroleum ether-soluble fraction of an indigenous Chinese tree Melicope pteleifolia (Rutaceae). The dihedral angle between the benzene rings is 2.7?(2)°. Intra-molecular O-H?O hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular O-H-O hydrogen bonds.
