Abstract：Using amaranth and dandelion as materials , the total reducing power and DPPH and hydroxyl radical scavenging effects were detected to compare the differences of antioxidant activity among different varie-ties.The activities of SOD and CAT and the contents of VC and flavone were also determined .The results showed that the antioxidant activity of red amaranth was higher than that of green amaranth , and that of micro-phyllous dandelion was higher than that of grandifoliate dandelion; the red amaranth had the highest antioxi-dant activity .The contents of main antioxidant components had large differences among the 4 potherbs , and their functions in total oxidation resistance needed further research.
