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