Abstract

Chestnut forest is one of the most fertile trees for humanity. It serves with both wood and non-wood products.  Polyphenols are important secondary metabolites of plant products and have a wide range of biological activities. In this study, the total polyphenol and flavanoid contents of chestnut products were investigated and compared. The samples were obtained from Zonguldak region of Turkey. Total polyphenol content (TPC) and total flavanoid content (TFC)  were determined Folin Ciocalteu's and Aluminum Chloride assays, respectively, TPC values were determined as 105 mg GAE/100, 536 mg GAE/100, 186 mg GAE/g and 128 mg GAE/g, respectively. The highest amount of TPC was detected in the propolis followed by the pollen, the blossom, and the honey.
