Summary:One of the products obtained from the fruit of the indigenous Australian tree Melicope ellyrana has been confirmed as the flavonoid pachypodol (4,5′‐di­hydroxy‐3,3′,7‐tri­methoxy­flavone), C18H16O7. This compound is similar to a number of the flavonones from the same species with the exception of the reduced side chain. The usual intramolecular hydrogen bonding between the hydroxy and the adjacent carbonyl or methoxy substituent groups is found, together with intermolecular hydrogen bonding between one of these hydroxy groups and a methoxy O atom [O⋯O 2.875 (4) Å], giving an infinite chain.
