Abstract

The present study aimed to investigate total flavonoid (TFC), cyanidin-3-glucoside (Cyd-3-glu) content, and antioxidant and antibacterial activities of ethanolic seed coat extract of two safflower genotypes (genotype C111 and A82) with contrasting seed coat colors. Despite the absence of Cyd-3-glu in seed coat extracts of white-seeded genotype C111 versus black-seeded genotype A82 and equal TFC index between the two genotypes, there was no significant difference in their antioxidant activity. Also, the ethanolic extract has growth inhibitory properties in pathogenic bacteria. It seems that differences in type and level of secondary metabolites of the seed coat with different color patterns can result in the ethanolic extract’s antioxidant activity. In addition, the results confirmed that seed coat color has not effect on the level (or severity) of the antibacterial properties of ethanolic seed coat extract.

种皮颜色对比红花乙醇提取物的抗氧化和抗菌活性

本研究旨在研究两种不同种皮颜色基因型(C111和A82)红花种皮乙醇提取物的总黄酮(TFC)、花青素-3-葡萄糖苷(Cyd-3-glu)含量及其抗氧化和抗菌活性。白籽C111和黑籽A82种皮提取物中不含Cyd-3-glu, TFC指数相同，但抗氧化活性差异不显著。此外，乙醇提取物对致病菌具有生长抑制作用。不同花色种皮次生代谢物的类型和水平的差异可能是影响乙醇提取物抗氧化活性的主要原因。此外，实验结果证实种皮颜色对乙醇种皮提取物的抑菌性能没有影响。

期刊介绍： ''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered. ''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
