Annotation. The aim of this study was to document the morphological characteristics of pollen grains and bee pollen of common buckwheat. Pollen grains were collected for the experiments from plants of common buckwheat harvested in Poltava region. Bee pollen was obtained from beekeepers in Poltava region. With scanning electron microscope the length of polar and equatorial axis of pollen grains were evaluated in range 27.60–36.64 μm and 13.07–18.99 μm respectively. For the bee pollen the average weight in the range 5.47–10.04 mg, height in the range 2.62–3.05 mm and width in the range 2.62–3.05 mm were determined. Statistically significant medium-strong dependence (r=0.479) between the weight and height of bee pollen was found. Antioxidant activity of bee pollen was determined with DPPH method. Antioxidant activity of aqueous / methanolic extracts of samples dried to 40 °C was 12.9 34.8 % and dried to 80 °C – 5.0/24.9 %.
