different caffeoyl-proline dipeptides (CA-Pro-Xaa-NH2), and evaluated their antioxidative activities with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and lipid peroxidation inhibition tests. Some of the CA-Pro-Xaa-NH2 showed higher free radical scavenging activities than CA, and even CA- CA-Pro-HisNH2. However, CA-Pro-His-NH2 still exhibited the highest antioxidative activity in reducing lipid peroxidation.
