In 1995 and 1996 field trials were performed to estimate total polyphenol contents in two potato varieties Agria and Karin from twelve localities. From two localities potatoes that have been cultivated in conventional and ecological alternative way were investigated. Polyphenol content was determined spectrophotometrically by Folin-Ciocalteau reagent at a wave length 765 nm. The polyphenol content of potato tubers is influenced by the genotype of the given variety, growing region and the way of growing and by specific features of the given year.
