Bioactive polyphenolic compounds from white cabbage cultivars
The aim was to analyse polyphenols and their antiradical activity in white cabbage cultivars Čepinski, Varaždinski, Ogulinski and Bravo from different geographical locations of Croatia. Polyphenols were analysed by using high- performance liquid chromatography (HPLC) and spectrophotometric methods (total polyphenols and total flavonoids), antiradical activity by using DPPH and ABTS methods. Caffeic, p- coumaric, ferulic and sinapic acids were identified. Total polyphenols, total flavonoids and polyphenols determined with HPLC (467 – 598, 104 – 166, 94 – 126 mg·kg-1 FW, respectively) and antiradical activity showed statistically significant variations. Varaždinski showed the highest polyphenol content, usually followed by Čepinski or Ogulinski while Bravo always showed the lowest polyphenol content. Principal component analysis showed clustering of all four cultivars. Čepinski, which was never analysed before, could be a valuable cultivar for further examination.
