ABSTRACT
Phenolic compounds are secondary metabolites that are quite widespread in nature. They play several physiological roles in plants where they occur, but many of them are also favorable to human health because of their antioxidant activity.[1]
Although very widespread, some of them can work as useful markers for the botanical and geographical origin of several plant products (wine, honey, coffee beans, and jams). These reasons led scientists to develop methods of analysis that are more and more reliable, sensitive, and informative.
