title: 1,3-Dihydr-oxy-2-methoxy-methyl-9,10-anthraquinone from Rennellia elliptica Korth.
abstract: The title compound, C(16)H(12)O(5), common name: lucidin ω-methyl ether, exists as a planar mol-ecule (r.m.s. deviation = 0.04 Å). Within the mol-ecule, the 1-hydr-oxy group forms a hydrogen bond to the adjacent carbonyl O atom, and the 3-hydr-oxy group forms a hydrogen bond to the adjacent meth-oxy O atom. The meth-oxy O atom is disordered over two positions of equal occupancy.
