The aim of this study was to determine the effect of cultivars on the concentration of antioxidant compounds: total carotenoid content (TC) and vitamin C (VC), and their correlation with the total antioxidant activity (TAA) in 65 potato cultivars () from 10 countries. The TC content revealed a highly significant effect of the year (Y), cultivar (C) and flesh colour (FC). The TC ranged from 101.5 µg 100 g DM (in cv. Kelly) to 715 µg 100 g DM (in cv. Mayan Gold). The TC values were weakly correlated with years and higher in yellow-fleshed potatoes than in white-fleshed potatoes (319.9 vs. 175.6 µg 100 g DM, respectively). The VC content ranged from 1.0 mg 100 g FM (in cv. Bzura) to 14.8 mg 100 g FM (in cv. Twinner). The content of VC were higher in yellow-fleshed (6.5 mg 100 g FM) than in white-fleshed potatoes (5.8 mg 100 g FM). The highest TAA were observed in cvs. Colleen, Basa, Triplo, Gatsby, Ditta, Twinner, Riviera, Michalina, Damaris, Belmonda, Ambo, Savinja, 12-LHI-6. For these cultivars, the FRAP values were 0.53 µmol TE 100 mg DM and DPPH 0.55 µmol TE 100 mg DM. The lowest TAA were observed in cvs.: Owacja, Mayan Gold, Kokra, Magnolia and Kelly. For them, the FRAP and DPPH values were slightly above 0.2 µmol TE 100 mg DM. It was shown that the concentration of TC in potato tubers has an impact on TAA.
总类胡萝卜素含量（TC）和维生素 C（VC），以及它们与 10 个国家的 65 个马铃薯品种（）总抗氧化活性（TAA）的相关性。TC 含量显示出年份（Y）、品种（C）和果肉颜色（FC）的高度显著影响。TC 范围从 101.5 µg 100 g DM（在 cv. Kelly 中）到 715 µg 100 g DM（在 cv. Mayan Gold 中）。TC 值与年份弱相关，黄肉马铃薯中的 TC 值高于白肉马铃薯（分别为 319.9 µg 100 g DM 和 175.6 µg 100 g DM）。VC 含量范围从 1.0 mg 100 g FM（在 cv. Bzura 中）到 14.8 mg 100 g FM（在 cv. Twinner 中）。黄肉马铃薯中的 VC 含量（6.5 mg 100 g FM）高于白肉马铃薯（5.8 mg 100 g FM）。在 cv. Colleen、Basa、Triplo、Gatsby、Ditta、Twinner、Riviera、Michalina、Damaris、Belmonda、Ambo、Savinja、12-LHI-6 中观察到最高的 TAA。对于这些品种，FRAP 值为 0.53 µmol TE 100 mg DM，DPPH 值为 0.55 µmol TE 100 mg DM。在 cv. Owacja、Mayan Gold、Kokra、Magnolia 和 Kelly 中观察到最低的 TAA。对于它们，FRAP 和 DPPH 值略高于 0.2 µmol TE 100 mg DM。结果表明，马铃薯块茎中 TC 的浓度对 TAA 有影响。
