摘要

亚麻籽含有丰富的营养、功能和有益健康的化合物。然而,亚麻籽的化学成分和生物活性化合物的含量可能存在很大差异,并可能受到基因型和环境等各种因素的影响。本研究评估并比较了六个实验种植亚麻籽品种的近似化学成分、木酚素含量和抗氧化潜力。在捷克共和国České Budějovice的南波西米亚大学实验站进行的对角线栽培试验在随后的三个生长季(2018、2019和2020年)进行。结果表明,栽培品种和生长条件影响了大部分研究参数。2019 年 5 月和 6 月的降水不足对种子产量和仲异落叶松脂素二葡萄糖苷含量产生了负面影响,但并未降低粗蛋白含量,而粗蛋白含量与含油量呈负相关。新开发的木脂素分析方法可以鉴定和量化仲异落叶松脂素二葡萄糖苷和马泰松脂素。它们的含量与总多酚含量和抗氧化测定(DPPH 和 ABTS 自由基清除活性)呈正相关,表明它们对亚麻籽的生物功能特性有重大贡献。另一方面,我们没有检测到亚麻籽的次要木酚素、松脂醇和落叶松脂醇。这项研究的结果表明,栽培品种和生长条件对亚麻籽化学成分和木质素含量的影响非常重要,它们决定了亚麻籽的营养和药用特性。

Comparison of Yield Characteristics, Chemical Composition, Lignans Content and Antioxidant Potential of Experimentally Grown Six Linseed (Linum usitatissimum L.) Cultivars.

Linseed represents a rich source of nutritional, functional and health-beneficial compounds. Nevertheless, the chemical composition and content of bioactive compounds may be quite variable and potentially affected by various factors, including genotype and the environment. In this study, the proximate chemical composition, lignans content and antioxidant potential of six experimentally grown linseed cultivars were assessed and compared. A diagonal cultivation trial in the University of South Bohemia Experimental Station in České Budějovice, Czech Republic, was established in three subsequent growing seasons (2018, 2019 and 2020). The results showed that the cultivar and growing conditions influenced most studied parameters. The lack of precipitation in May and June 2019 negatively affected the seed yield and the level of secoisolariciresinol diglucoside but did not decrease the crude protein content, which was negatively related to the oil content. The newly developed method for lignans analysis allowed the identification and quantification of secoisolariciresinol diglucoside and matairesinol. Their content correlated positively with the total polyphenol content and antioxidant assays (DPPH and ABTS radical scavenging activity), indicating the significant contribution to the biofunctional properties of linseed. On the other hand, we did not detect minor linseed lignans, pinoresinol and lariciresinol. The results of this study showed the importance of cultivar and growing conditions factors on the linseed chemical composition and the lignans content, determining its nutritional and medicinal properties.
