Antioxidant activity of polyphenolic compounds in Camphotree leaves

The caphotree was a new polyphenol resource with high safety.The effect of polyphenolic compounds in Camphotree leaves on scavenging free radicals and the lipid oxidation of fat was studied and compared among free polyphenol,combined polyphenol,and resin purified polyphenol.The results showed that polyphenol in Camphotree leaves had great ability to scavenge free radicals(·OH,DPPH·,and O2 ·).At the same concentration,resin purified polyphenol behaved the best antioxidant activity,which was similar to VE or better than VE.In addition,the polyphenolic compounds in Camphotree leaves showed activity of inhibiting lipid oxidation.
