| Abstract: | Scavenging activity of four natural flavonoids to 2,2-diphenyl-1-picrylhydrzyl free radical(DPPH) was studied by cyclic voltammetry and differential pulse voltammetry.The results show that the method can be successfully used to screen compounds for free radical scavenging activities using DPPH.And the sensitivity of the method is high with minor error,making it effective for detection of free radical DPPH and scavenging the free radical. |
| Keywords: | natural flavonoid 2 2-diphenyl-1-picrylhydrzyl cyclic voltammetry differential pulse voltammetry |
