Cloudberry (Rubus chamaemorus L.) is the leader among northern berries in content of phenolic compounds, which can cause a wide range biological activity. Currently, there an increased interest study antioxidant activity plant extracts order to search for promising sources raw materials pharmaceutical and food industries. The article presents results comparative analysis interpopulation gender differences antiradical activities vitro cloudberry leaf growing on territory Republic Belarus. Classical spectrophotometric methods were used determination: phosphomolibdenic method, Fe + 2-chelating activity, NO-inhibiting inhibition hydroxyl radicals (OH), method superoxide radical alkaline solution dimethylsulfoxide, DPPH, ABTS. Differences compounds flavonoids alcoholic blades Rubus L. It was found that population Bolshoi Mokh preserve possesses highest rates radicals. maximum iron-chelating exhibited by male Bolshoy Moh preserve. least inhibitory shown nitrogen-oxide radical. established values activities, as well may be important development measures species specific populations southern border habitat.
