Eight prenylated flavonoids, including three new compounds, have been isolated from chloroform extracts of stems and leaves of Maclura pomifera. The new prenylated flavonoids have been characterized as 5,7,4',2"-tetrahydoxy-6-[3"-methyl-but-3"-enyl]-flavone, 5,4'-dihydroxy-2"-(1-hydroxy-1-methylethyl)- 3"-methoxyfurano (4",5" (6,7) isoflavone and 5,4'-dihydroxy-2"-(1-hydroxy-1-methylethyl)- 3"-methoxyfurano (4",5" (6,7) flavone. The structures were elucidated using spectroscopic methods.
