title: 5,7-Dihydr-oxy-3,6,8-trimethoxy-flavone.
abstract: 5,7-dihydr-oxy-3,6,8-trimeth-oxy-4H-chromen-4-one), C(18)H(16)O(7), is a flavone that was isolated from Ainsliaea henryi. There are two mol-ecules in the asymmetric unit, one of which has a disordered meth-oxy group [occupancy ratio 0.681 (9):0.319 (9)]. Both mol-ecules have an intra-molecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are linked into O-H⋯O hydrogen-bonded chains parallel to [110].
