ABSTRACT
This chapter covers the determination of phenolic compounds by HPLC, which are ubiquitously found in the plant kingdom as secondary metabolites exerting a range of important functions in plants. Polyphenols are also of increasing interest for their technofunctional properties, such as color and antioxidant activity, but even more interesting due to their putative health-promoting properties. Even though anthocyanins form one of the most important subclasses of polyphenols, they are not considered here because a separate chapter (Chapter 22) is dedicated to pigments.
