"... high quality book that contains much more than a straight forward catalogue of the methods used in purify and identify polyphenols ... The book is an essential reference for anyone working on the analysis of polyphenols, it is an extremely rich source of information for the experienced investigator and even more so for new comers to the field. It is a book which will be consulted routinely (my copy is already "well-thumbed") and not one that gathers dust, unused on the top shelf of a bookcase."
