It is widely distributed and cultivated throughout tropics from West Africa to Pacific islands (as far) Eastas Tahiti. It blossoms during March to October. Fresh flowers of calophyllum inophyllum have been treated for their flavonoids contents. They are rich flavonol quercetin and flavonol glycosides quercitrin. They have been characterized with the help of modern physical methods like UV, H-1 NMR , C-13 NMR, chemical reactions, chromatographic techniques and hydrolytic studies.
