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.

用常规、有机和生物动力学方法种植的彩色马铃薯 (Solanum Tuberosum L.) 品种中生物活性化合物的表征

本研究的目的是评估传统、生物动力和有机栽培方法对不同颜色果肉马铃薯品种块茎中多酚和类胡萝卜素含量的影响：“红艾玛莉”、“沙拉蓝”、“紫罗兰”、 “龙卷风”和“劳拉”。这些生物活性化合物通过高效液相色谱法测定。收到的数据用方差分析进行分析，并通过主成分分析进一步探索和可视化。与传统块茎相比，生物动力和有机样品中的多酚 (sum)、酚酸 (sum)、绿原酸、对香豆酸和咖啡酸含量更高。此外，有机和生物动力法生产的马铃薯（“沙拉蓝”品种除外）明显富含类黄酮和花青素。在生物动力马铃薯中发现了最高含量的类胡萝卜素（总和）、叶黄素和β-胡萝卜素。在被测品种中，果肉为白色的“龙卷风”的多酚（sum）、酚酸（sum）、绿原酸和对香豆酸含量最高。“紫罗兰”果肉呈深紫色，黄酮类（sum）、花青素（sum）、矮牵牛素-3,5-di-O-glucoside、pelargonidin-3,5-di-O-glucoside和peonidin的含量最高-3,5-二-O-葡萄糖苷。类胡萝卜素仅在“劳拉”块茎中发现，占主导地位的类胡萝卜素是叶黄素。积累了最高含量的黄酮类化合物 (sum)、花青素 (sum)、petunidin-3,5-di-O-glucoside、pelargonidin-3,5-di-O-glucoside 和 peonidin-3,5-di-O-糖苷。类胡萝卜素仅在“劳拉”块茎中发现，占主导地位的类胡萝卜素是叶黄素。积累了最高含量的黄酮类化合物 (sum)、花青素 (sum)、petunidin-3,5-di-O-glucoside、pelargonidin-3,5-di-O-glucoside 和 peonidin-3,5-di-O-糖苷。类胡萝卜素仅在“劳拉”块茎中发现，占主导地位的类胡萝卜素是叶黄素。
