Popis: Boldine (5,6,6a,7-tetrahydro-1,10-dimethoxy-6-methyl-4H-dibenzo[de, g]quinoline-2,9-diol) is an aporphine alkaloid noted for its anti­oxidant properties. A salient feature of the mol­ecule is the non-planarity of the biphenyl system, which exhibits a dihedral angle of 151.1 (1)° between the least-squares planes of the two benzenoid rings and torsion angles of 25.7 (3), −150.6 (2), −155.9 (2) and 27.8 (3)° about the biphenyl bond. Methoxyl carbon atom C13 lies only 0.195 (4) A above the mean plane of the ring to which it is attached, with torsion angles about the C10—O2 bond of 168.6 (2) and −11.3 (4)°. Methoxyl carbon atom C14 is displaced −1.101 (3) A away from the corresponding ring plane, with torsion angles about the C1-O3 bond of 102.3 (2) and −79.7 (3)°. All intramolecular bonds and angles are within the expected range.
