We investigated the reaction rate on DPPH radical scavenging reaction using 6-gingerol and 6-shogaol as the constituents of ginger having a guaiacol skeleton. Furthermore, we investigated the reaction rate of vanilin, guaiacol, 4-vinylguaiacol as the several kinds of guaiacol related compounds. As a result, we revealed that the order of reaction rate on DPPH radical scavenging reaction of five guaiacol related compounds is 4-vinylguaiacol＞6-gingerol＞6-shogaol＞guaiacol＞vanilin. And also, the strength of DPPH radical scavenging ability of guaiacol related compounds under the coexistence of two kinds of antioxidants was evaluated the order of 4-vinylguaiacol＞6-gingerol＞6-shogaol＞guaiacol＞vanilin. Finally, we revealed that electric effect on 4-position substituent of guaiacol skeleton was the relationship of the reaction rate on DPPH radical scavenging reaction and DPPH radical scavenging ability of guaiacol related compounds under the coexistence of two kinds of antioxidants.
