Two different NokJoongTangs were prepared by boiling antler and various oriental medicinal materials. The phenolic contents and free radical scavenging effects against DPPH(1,1-diphenyl-2-picrylhydrazyl) radical and hydroxyl radical of the NokJoongTangs which are used as the health supplement foods, were investigated. NokJoongTang-II prepared dried antler with various oriental medicinal materials, had higher phenolic content than that of NokJoongTang-I prepared 1mm raw antler with the same materials. In addition, NokJoongTang-II exhibited higher scavenging activities than these of NokJoongTang-I against DPPH radical and hydroxyl radical. These result indicate that free radical scavenging activity of NokJoongTang showed a difference by using raw and dry antler for NokJoongTang preparation, and that the findings also show a positive correlation between radical scavenging activity and total phenolic contents.
