摘要：

The antioxidant activity test of Celosia cristata antiviral proteins (CCP-25 and CCP-27) using ferric reducing antioxidant power (FRAP) assay in vitro indicated that these proteins are strong antioxidants. The increase in activities of redox-enzymes such as peroxidase, catalase and polyphenol oxidase on tobacco mosaic virus (TMV) inoculation of test plants, was inhibited when plants were treated with CCP-25 before TMV inoculation. The activity of phenylalanine ammonia lyase, involved in biosynthesis of antioxidative compounds was also inhibited. This is the first ever report where plant antiviral proteins have been shown to have strong antioxidative property. A possible correlation between antioxidant activity of CCPs and their antiviral activity is speculated.
