Antioxidant activity and content of selected antioxidant compounds in grain of different oat cultivars
The total antioxidant activity (TAA), total contents of polyphenols (TPC), phenolic acids (TPA) and tocols (TTC) were determined in the grain of 5 oat cultivars of Czech origin grown under organic and conventional cropping systems in two-year experiments (2018 and 2019). The TPC ranged from 772.9 mg...

| Summary: | The total antioxidant activity (TAA), total contents of polyphenols (TPC), phenolic acids (TPA) and tocols (TTC) were determined in the grain of 5 oat cultivars of Czech origin grown under organic and conventional cropping systems in two-year experiments (2018 and 2019). The TPC ranged from 772.9 mg/kg DM (dry matter) (hulled oat cv. Seldon) to 890.6 mg/kg (naked oat cv. Patrik); the TPA from 261.6 mg/kg (cv. Seldon) to 479.0 mg/kg (cv. Patrik); the TTC from 110.9 mg/kg (hulled oat cv. Korok) to 126.5 mg/kg (cv. Seldon). The TAA ranged from 427.1 mg/kg (cv. Korok) to 474.9 mg/kg (cv. Seldon). Besides the effect of the cultivar, the TAA and antioxidant contents were significantly affected also by year (weather conditions); higher values were observed in the drier and warmer the year 2019. The effect of the cropping system was statistically insignificant. |
