Eight prenylated flavonoids, including three new compounds, have been isola
ted from chloroform extracts of stems and leaves of Maclura pomifera a. The
new prenylated flavonoids have been characterized as 5,7,4',2 "-tetrahydox
y-6-[3 "-methyl-but-3 "-enyl]-flavone, 5,4'-dihydroxy-2 "-(1-hydroxy-1-meth
ylethyl)-3 "-methoxyfurano (4 ",5 " (6,7) isoflavone and 5,4'-dihydroxy-2 "
-(1-hydroxy-1-methylethyl)-3 "-methoxyfurano (4 ",5 " (6,7) flavone. The st
ructures were elucidated using spectroscopic methods. (C) 1998 Published by
