The ability of curcumin to inhibit free radical reactions can be used in the prevention of diseases such as cancer and coronary heart disease. UV-Vis spectrophotometric and chemiluminescent dynamic methods for determination of the antioxidant activity of curcumin were developed. The spectrophotometric method includes investigation of the interaction between DNA, isolated from HL-60 cells, and curcumin. The decreasing absorption of curcumin in the presence of HL-60 DNA against the blank sample can be a measurement for some complex formation between curcumin and DNA. The chemiluminescent method involves three tests for the detection of luminol- dependent chemiluminescence based on model systems that generate superoxide, hydroxide and hypochlorite radicals. The strongest decay of chemilunimescence was registered at the highest concentration of curcumin (100 mu mol L-1).
