摘要: 为研究富硒对雪樱子成分的影响,测定富硒和非富硒雪樱子中健康有益成分含量并进行对比分析。在超高效液相色谱-串联质谱代谢组学技术分析雪樱子成分的基础上,根据所含成分的丰度测定雪樱子根、茎、叶、花4 个部位的多酚、黄酮、矿物质含量,并比较富硒与非富硒雪樱子中这类物质含量的差异。结果发现富硒雪樱子的多酚、黄酮、矿物质含量(锌除外)普遍高于非富硒雪樱子,其中富硒雪樱子叶片的含量变化最明显,多酚含量增长65.9%,黄酮含量增长95.4%,钙含量增长39.5%,铁含量增长16.8%,铜含量增长297.5%,硒含量增长1 050.0%,钼含量增长110.7%,钴含量增长300.0%,铬含量增长207.7%,而锌含量降低76.4%。上述数据表明富硒促进了雪樱子各部位中多酚、黄酮及大多数矿物质含量的提升。因此,探讨富硒雪樱子的健康有益成分的变化,可为富硒雪樱子保健产品的开发提供理论依据。

Abstract: In order to study the effect of selenium enrichment on chemical composition of Amaranthus caudatus L. (ACL), we determined and comparatively analyzed the health-benefiting components (polyphenols, flavonoids and minerals) in the roots, stems, leaves and flowers of Se-enriched and non-Se-enriched ACL by metabonomics based on ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The results showed that the contents of polyphenols, flavonoids and minerals (except zinc) in Se-enriched ACL were generally higher than those in normal ACL. Among the four plant parts, the leaves of Se-enriched ACL showed the greatest changes in the contents of these components, exhibiting an increase in the contents of polyphenols, flavonoids, calcium, iron, copper, selenium, molybdenum, cobalt and chromium of 65.9%, 95.4%, 39.5%, 16.8%, 297.5%, 1 050.0%, 110.7%, 300.0% and 207.7%, respectively and a 76.4% decrease in the content of zinc compared to the non-Se-enriched ones. The above data showed that selenium enrichment promoted the accumulation of polyphenols, flavonoids and most minerals in different parts of ACL. This study may provide a theoretical basis for the development of health products from Se-enriched ACL.
