| Summary: | The content and antioxidation activity of total flavonoids extracted from 5 species of Dryopteridaceae plants were studied by aluminum color spectrophotometry.The results showed that the 5 species of Dryopteridaceae plants contained flavonoids,which content ranged from 5% to 8%.<i>Dryopteris lacera</i> appeared the highest total flavonoid content(8.24%);<i>D.atrata</i> and <i>D.varia</i> appeared the lowest(5.01%).The total flavonoids content of <i>Polystichum tripteron</i>(5.2%) and <i>D.peninsulae</i>(6.53%) are in the middle. The flavonoids extracted from the 5 species of Dryopteridaceae plants show a good antioxidant activity,and the content of flavonoids extracted from the plants was in direct proportion to the antioxidation(Iron reducing power,DPPH free radical scavenging activity,ABTS<sup>+</sup>scavenging activity).This paper is to provide a reference to the development and utilization of Dryopteridaceae plants. |
