Abstract

In this study the content of total polyphenolics, rutin, and antioxidant activity in different anatomical parts of common buckwheat plants (Fagopyrum esculentum Moench.) of six cultivars (Spacinska, Emka, Kasho, Jana C1 and Hrusowska) was analyzed. Antioxidant activity in plant material was determined by free radical DPPH. Highest antioxidant activity was assessed in leaves, whereas stems had the lowest antioxidant activity. Total polyphenol content was assessed spectrophotometrically by the Folin-Ciocalteu assay. The highest concentrations were detected in leaves, with values ranging from 68.74 to 90.27 g gallic acid equivalents kg−1, while the lowest concentrations were measured in stems (2.88–3.12 g.kg−1). Significant differences between the anatomical parts were confirmed also for rutin content with the exception of cultivars Kasho and Jana C1, where the rutin content in stem and seeds was not statistically different. The highest concentration of rutin (37.90 g.kg−1) was determined in leaves of cultivar Pyra.
