FLAVONOID CHROMATOGRAPHIC PROFILES AND PHENOLIC-ACID DETERMINATION IN4 MAIZE LINES

Flavonoid chromatographic profiles were determined and chlorogenic and ferulic acid were quantified in 4 maize lines with different response s against attack by Spodoptera frugiperda (J.E. Smith), and at two lea f growth stages. In the two leaf growth stages and in the 4 lines ther e were differences in the flavonoid profiles, both in the number of sp ats and in the phenolic acids amounts. These results may indicate a po tential role far the analized compounds in leaf resistance against ins ect attack.
