Basicaly You might use as a starting point following reference:
=46lavonoids can protect maize DNA from the induction of ultraviolet
radiation damage. Ann E. Stapleton, and Virginia Wallbot
Plant Physiol (1994) 105: 881-889
Last time I tried to search some papers describing flavonoids in maize (it
was long time ago) there was nothing except shown above.
good luck
