Publisher Summary This chapter discusses the antioxidant activities of bile pigments—
biliverdin and bilirubin. Biliverdin and bilirubin are potent scavengers of singlet oxygen. The
methods described in the chapter apply to the measurement of the peroxyl radical
scavenging activity of biliverdin and the various biological forms of bilirubin. Most of the
methods are applicable to testing the antioxidant activity of other compounds. The method is
based on the thermal decomposition of an azo compound under aerobic conditions whereby …
