Biological activities of Sorbus aucuparia L. leaves extract was tested in our study. Antineurodegenerative activity was evaluated by acetylcholinesterase (AChE) and tyrosinase (TYR) inhibitory activity assays while antioxidant activity was by tested using four different assays. In all antioxidant test we noticed concentration dependent activity of ...
