Characterization of Bioactive Compounds in Colored Potato (Solanum Tuberosum L.) Cultivars Grown with Conventional, Organic, and Biodynamic Methods
The purpose of this research is to evaluate the effect of conventional, biodynamic, and organic cultivation methods on the contents of polyphenols and carotenoids in tubers of potato cultivars with different colored flesh: “Red Emmalie”, “Salad Blue”, “Violetta”, “Tornado”, and “Laura”. These bioactive compounds were determined by the high-performance liquid chromatography method. The data received were analyzed with ANOVA and further explored and visualized by principal component analysis. Higher contents of polyphenols (sum), phenolic acids (sum), chlorogenic acid, p-coumaric acid, and caffeic acid were found in biodynamic and organic samples compared to the conventional tubers. Moreover, organically and biodynamically produced potatoes (except “Salad Blue” cultivar) were significantly richer in flavonoids and anthocyanins. The highest contents of carotenoids (sum), lutein, and β-carotene were found in biodynamic potatoes. Among the tested cultivars, “Tornado”, with white flesh, was richest in polyphenols (sum), phenolic acids (sum), chlorogenic acid, and p-coumaric acid. “Violetta”, with dark purple flesh, accumulated the highest contents of flavonoids (sum), anthocyanins (sum), petunidin-3,5-di-O-glucoside, pelargonidin-3,5-di-O-glucoside, and peonidin-3,5-di-O-glucoside. Carotenoids were only found in “Laura” tubers, and the dominating carotenoid was lutein.
