摘要:Flavonoid compounds, namely 2’,6’-dihydroxy-4’-methoxydihydrochalcone, kaempferol, and quercetine had been separated from the aerial part of the fern Pityrogramma calomelanos. Their structures were elucidated based on the spectroscopic evidence and by comparison with reported literature data. All isolates showed cytotoxicity against the murine leukemia P-388 cells.
