摘要：

The title compound, C17H14O5, a flavone, was isolated from the rhizomes of Kaempferia parviflora. There are two crystallographically independent molecules in the asymmetric unit. The molecular structure is stabilized by intramolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds. C-H center dot center dot center dot O intermolecular hydrogen bonds and pi-pi stacking interactions link the molecules into a network.
