6种菊花抗氧化活性及总酚含量的研究

摘要

采用DPPH、ABTS和FRAP 3种方法测定了6种菊花的抗氧化活性并用福林-酚法测定其总酚含量.结果表明:依据其总酚含量和抗氧化活性,6种菊花均是很好的抗氧化剂来源.FRAP、DPPH和ABTS试验显示,黄金菊的抗氧化活性最强,其FRAP、DPPH和ABTS值分别为150.22、125.19、173.47μmol Trolox/g.此外,总酚测定结果表明,黄金菊的总酚含量最高.%DPPH, ABTS and FRAP methods were used to determine the antioxidant activities of six kinds of chrysanthemum [Dendranthema morifolium(Ramat.) Tzvel], and Folin-Ciocalteu method was used to determine their total phenolic contents. Results indicated that six kinds of chrysanthemum were significant sources of an-tioxidants in terms of their total phenolic contents and antioxidant activities. In FRAP, DPPH and ABTS assays, chamomile (Perennial chamomile) exhibited the highest antioxidant activity with the values of 150.22, 125.19μmol Trolox/g and 173.47μmol Trolox/g respectively. In addition, in Folin-Ciocalteu assay, chamomile exhib-ited the highest total phenolic content.
