Abstract：
The ability of brassicas to accumulate selenium is crucial for their positive effects on health. Selenium improves the immune system and the antioxidant defenses. Selenium biofortification of brassicas has therefore been explored to increase dietary selenium intake in humans. However, the effects of selenium biofortification on bioactive compounds, mainly phenolic compounds, are not clear. So, this systematic review and meta-analysis aimed to answer the question \'What are effects of the biofortification of brassicas with selenium on total phenolic compounds?\' Ten studies, which assessed the effect of selenium biofortification on total phenolic compounds, were selected for qualitative synthesis and four studies were included in the meta-analysis after a thorough literature review of the PubMed, Science Direct, and Web of Knowledge databases. The quality of the evidence ranged from high to moderate. The meta-analysis results indicated that the total phenolic compound content was significantly higher (P = 0.002) in the supplemented group but the results showed considerable heterogeneity (P < 0.00001, I2 = 97%) between studies. This systematic review and meta-analysis summarizes the effect of Se biofortification on the increase in the content of total phenolic compounds and it suggests that several factors can affect this relationship. © 2023 Society of Chemical Industry.
摘要：
油菜积累硒的能力对健康产生积极影响至关重要。硒改善免疫系统和抗氧化防御。因此,已经探索了芸苔属植物的硒生物强化，以增加人类饮食中的硒摄入量。然而,硒生物强化对生物活性化合物的影响，主要是酚类化合物，不清楚。所以,本系统综述和荟萃分析旨在回答以下问题：“用硒生物强化油菜对总酚类化合物有什么影响？”十项研究，评估了硒生物强化对总酚类化合物的影响，选择进行定性综合，在对PubMed进行全面文献综述后，四项研究被纳入荟萃分析，ScienceDirect和WebofKnowledge数据库。证据的质量从高到中等不等。根据荟萃分析结果，总酚类化合物含量显著高于(P=0.002),但结果显示研究之间存在相当大的异质性(P<0.00001,I2=97%).本系统综述和荟萃分析总结了硒生物强化对增加总酚类化合物含量的影响，以及几个因素可能影响这种关系。本文受版权保护。保留所有权利。
