Abstract

The aim of this study was to compare the antioxidant potential in the fruits of different hybrids of Rubus idaeus and Rubus occidentalis (four hybrids) against the fruit of known cultivars of both species (R. idaeus-three cultivars; R. occidentalis-five cultivars) and, using chemometric analysis, to select factors affecting the level of polyphenols and antioxidant properties. Antioxidant activity was determined using the ABTS, DPPH and FRAP tests. Chemometric analysis enabled the separation of R. idaeus and R. occidentalis cultivars and classified the hybrid R. idaeus/R. occidentalis R1314701 as belonging to the R. occidentalis species. Moreover, two hybrids, Rubus occidentalis/Rubus idaeus R1613411 and R. idaeus/R. occidentalis R1613409, can be classified as a purple raspberry. Crossbreeding species/cultivars of the Rubus genus may result in an increased content of anthocyanins, but on the other hand, it may lead to a reduction in free radical scavenging activity in the ABTS and DPPH. Spearman's correlations confirm the correlations between the total polyphenol content and antioxidant activity in the DPPH, ABTS and FRAP, as well as the anthocyanin content and antioxidant activity in the ABTS and FRAP tests. Chemometric analysis can be an effective tool in determining the species affiliation of obtained hybrids and cultivars.

本研究的目的是比较茜草和西洋茜草不同杂交种（四个杂交种）果实的抗氧化潜力与这两个物种的已知栽培品种（茜草-三个栽培品种；西洋茜草-五个栽培品种）果实的抗氧化潜力，并使用化学计量分析法选择影响多酚水平和抗氧化特性的因素。使用 ABTS、DPPH 和 FRAP 试验测定抗氧化活性。化学计量分析将 R. idaeus 和 R. occidentalis 种植品种区分开来，并将杂交种 R. idaeus/R. occidentalis R1314701 归类为 R. occidentalis 种。此外，Rubus occidentalis/Rubus idaeus R1613411 和 R. idaeus/R. occidentalis R1613409 这两个杂交种也可归类为紫树莓。茜草属物种/栽培品种杂交可能会导致花青素含量增加，但另一方面也可能导致 ABTS 和 DPPH 自由基清除活性降低。斯皮尔曼相关性证实了 DPPH、ABTS 和 FRAP 试验中总多酚含量与抗氧化活性之间的相关性，以及 ABTS 和 FRAP 试验中花青素含量与抗氧化活性之间的相关性。化学计量分析是确定所获杂交种和栽培品种品种归属的有效工具。
