Phenol-Explorer is the first comprehensive database on polyphenol content in foods. The database contains more than 35,000 content values for 500 different polyphenols in over 400 foods. These data are derived from the systematic collection of more than 60,000 original content values found in more than 1,300 scientific publications. Each of these publications has been critically evaluated before inclusion in the database. In addition, reports commenting on the factors influencing polyphenol content are available for each food group. Major sources of variability in polyphenol content are described with over 400 literature references.
Release 2.0 of Phenol-Explorer adds comprehensive data on polyphenol metabolism. Pharmacokinetic data on 380 metabolites identified in biofluids after the consumption of polyphenol-rich sources are presented. These data have been extracted from 236 publications and originate from 221 intervention studies in human subjects and experimental animals.
Phenol-Explorer 2.0 also allows the download of the whole database on the polyphenol composition of foods.
A wide range of queries on foods, polyphenols and metabolites, as identified by various analytical methods, can be executed. Simple queries can be made by typing the name of a polyphenol, metabolite or food source at the top of any page. More complex queries can be performed by using the Advanced search. In this search, two or more foods or polyphenols can be selected, to easily compare for example the contents of the various polyphenols in green and black tea. Clicking on the different icons enable tabular data to be displayed in different ways. Using the ‘Advanced display option’ it is also possible to sort results as desired and to calculate total polyphenol contents per class and subclass.
Phenol-Explorer has been developed at INRA in collaboration with AFSSA, the University of Alberta, the University of Barcelona and In Siliflo. The work has been made possible thanks to the financial support of the French government, Unilever, Danone and Nestlé.
We wish you a fruitful polyphenol exploration!
