reaction. On this basis
a flow injection procedure combined with inhibited chemiluminescence detection was developed for the determination of these compounds. The method is fast
simple and sensitive. These polyphenols were detectable at picomolar levels. Furthermore
the mechanism of chemiluminescence inhibition by polyphenols was proposed to be due to the reaction between polyphenol and radical intermediates of chemiluminescent reaction.
