The Agrimonia species have been reported to possess several biological activities, such as antioxidant, anti-inflammatory, antiviral, antibacterial, anti-diabetic, diuretic (Copland et al., 2003; Kwon et al., 2003; Shin et al., 2010). Decoction can be used in traditional medicine for a treatment of diabetes mellitus or coronary diseases (Gray and Flatt, 1998; Correia et al., 2006). Inhibitors of α-glucosidase are promising drugs in the treatment of diabetes mellitus, and antioxidants from natural sources can prevent the oxidative stress associated with diabetes mellitus. The individual with diabetes has a 2- to 6-fold increased risk of cardiovascular disease (Wolff, 1993) and Agrimonia herbs could exert a beneficial effect in the diabetic environment. A. eupatoria is the most common Agrimonia species in Europe and the aerial parts are used in form of infusion, decoction or tincture. The scientific investigations are focused on research of the most common A. eupatoria and A. pilosa (Jung et al., 2010; Kato et al., 2010; Lee et al., 2010), there are no information about species growing in eastern Asia – A. japonica and A. coreana. In this work, the phytochemical profile of five Agrimonia species was investigated and its correlation with antioxidant activity and inhibition of α-glucosidase was verified
