Rezension

"Overall, this book is packed with interesting information, resulting from the lifetime's work of some of the editors." (Chromatographia., 17 April 2014)
 
"As such the book would serve as an excellent introduction for scientists wanting to transfer into the area, or as a useful state of the art overview for those in the field. Highly recommended." (Chemistry & Industry, 1 July 2012)
 
"Additionally, this text should be included in all college and university science and medical libraries, as there are no comparable up-to-date treatises on the health benefits, composition, and bioavailability of teas, coffee, and cocoa." (HerbalGram, 2012)
 
"Highly recommended. Lower-division undergraduates through professionals and general readers interested in human medicine, natural health, or plant biology." (Choice, 1 May 2012)
