Pomiferin is a prenylated isoflavone that can be found along with osajin in the fruits and female flowers of the osage orange tree ( Maclura pomifera).
Pomiferin was identified and named in 1939 by Melville L. Wolfrom from Ohio State University. In 1941, Wolfram classified pomiferin as an isoflavone and in 1946 published the complete structure of Pomiferin. In 2003 the crystal structure of pomiferin (3-(3,4-dihydroxyphenyl)-5-hydroxy-8,8-dimethyl-6-(3-methylbut-2-enyl)-4H,8H-pyrano[2,3-h]chromen-4-one), CHO was reported by J. Marek.
In recent research Pomiferin has demonstrated efficacy as an antioxidant, cardioprotectant, antimicrobial, antidiabetic, PDE5 inhibitor and cytotoxicity for several cancer cell lines.
