The bioactive compounds and the level of antioxidant activity of these cultivars were determined and compared. The presence of polyphenols (flavonoids and phenolic acids) in the investigated samples was studied by Fourier transform infrared (FT-IR) spectroscopy. By far the highest levels of polyphenols and ascorbic acids were found in 'Bidan', which also contained the highest levels of protocatechuic and vanillic acids. In addition, the level of antioxidant activity was significantly higher in 'Bidan' for CUPRAC, ABTS, DPPH and FRAP radical scavenging assays, respectively). Pattern-recognition techniques were used to compare the cultivars. A high correlation was found among the polyphenols, ascorbic acid and the antioxidant activity in the studied cultivars.
