Phenolic compounds are antioxidants present in a great number of vegetal foods. There are many studies that report beneficial health effects of them. In Argentina there is no information about the polyphenol content of their foods. The aim of this study was to develop a program to compile polyphenol content data from different sources and also generated in our laboratory, to elaborate a Database.An informatic tool was developed and the data were obtained from scientific publications and laboratory reports from different regions of Argentina. Information on foods, polyphenols, and analytical methods were included.The Data Base contains data of over a hundred of food items grouped into five groups with the following items each one: Cereals, legumes and starches (61), Vegetables (11), Fruits (16), aromatic species (8), by-products (35). When averaging the contribution of phenolic compounds per group (those expressed in mgGAE/100g and determined with Folin for the comparison) were selected, the following decreasing order was established: by-products (313.6 mgGAE / 100 g); Aromatic species (299.15 mg GAE / 100 g); vegetables (200.42 mg GAE / 100 g); Cereals, legumes and starches (150.2 mg GAE / 100 g); Fruits (139.7 mg GAE / 100g)For many local products, the polyphenol composition is much less known. Due to polyphenol content in a given food may vary greatly according to variety, agricultural conditions, storing and processing conditions, the database allows comparing the result of the data included with other databases such as phenol-explorer and the Chilean database. When compared blueberries (Vaccinium corymbosum L.) data on polyphenols content from local data were similar to results extracted from phenol-explorer and The New database of Chile of fruits and vegetables produced and consumed within the south Andes region of South America (433mg GAE/100gFW). However, in the case of Andean potatoes, not only there is no information in international databases, but it is also important to determine the variability within the same group, the mean was and th standard deviation was .Here the importance of having data of autochthonous foods and own. All these new data will be incorporated into the National Food Composition Database (FCDB) and National Food Composition Table (FCT).
