title: 3-Hy-droxy-2-[(4-hy-droxy-3,5-dimeth-oxy-phen-yl)(2-hy-droxy-4,4-dimethyl-6-oxo-cyclo-hex-1-en-1-yl)meth-yl]-5,5-dimethyl-cyclo-hex-2-en-1-one.
abstract: In the title compound, C(25)H(32)O(7), the 3-hy-droxy-5,5-dimethyl-cyclo-hex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intra-molecular hy-droxy-ketone O-H⋯O inter-action between the two substituted cyclo-hexane rings as well as a short intra-molecular phenol-meth-oxy O-H⋯O inter-action.
