摘要

本研究旨在检测九种靛蓝的植物化学成分和抗氧化成分的差异。为此,使用铁还原抗氧化能力(FRAP)、DPPH自由基清除、铁离子螯合活性、磷钼还原能力、脱氧核糖降解、β-胡萝卜素漂白、一氧化氮清除和超氧化物自由基清除测定来评估该物种的总酚含量、类黄酮含量和抗氧化活性。总酚类和黄酮类化合物的含量在1.33~22.5之间 mg TAE/g植物材料和0.47至5.02 mg QE/g植物材料,而用不同的抗氧化测试模型测试的抗氧化活性因所研究的物种以及用于提取的溶剂而异。有趣的是,所有测试的提取物都表现出相当大的清除自由基的活性,此外,在所研究的物种中,发现毛藻、腺藻、林藻、何首乌、林叶藻和三叶藻是最有效的。结果表明,不同物种的植物化学成分和抗氧化活性存在显著差异。Pearson相关系数分析显示酚类和黄酮类化合物与抗氧化活性显著相关。

Disparities of phytochemical constituents and antioxidant activities of some Indigofera species
The current study was intended to examine the difference in the phytochemical and antioxidant profile of nine Indigofera species. With this aim, the species were assessed for total phenolic content, flavonoid content, and antioxidant activity using ferric reducing antioxidant power (FRAP), DPPH free radical scavenging, ferrous ion chelating activity, phosphomolybdenum reducing power, deoxyribose degradation, β-carotene bleaching, nitric oxide scavenging, and superoxide radical scavenging assays. The content of total phenolics and flavonoids ranged from 1.33 to 22.5 mg TAE/g plant material and 0.47 to 5.02 mg QE/g plant material respectively in the various species, while the antioxidant activity as tested with different antioxidant test models varied with the species studied as well as with the solvents used for the extraction. Interestingly, all the tested extracts demonstrated considerable free radical scavenging activity, moreover, I. hirsuta, I. glandulosa, I. linnaei, I. hochstetteri, I. linifolia, and I. trita were found to be the most effective among the species studied. The results indicated the significant differences in phytochemical constituents and the antioxidant activity among the species. The Pearson correlation coefficient analysis exhibited a significant correlation of phenolics and flavonoids with the antioxidant activity.
