dc.description.abstractBoldine, in low micromolar concentrations, was able to prevent brain bomogenate autooxidatíon, the 2,2'·uobis(2·amidinopropane)(AAP)·induced Iipid peroxidation of red cell plasma rnembranes, and the AAP·induced inactivation of Iysozyrne. These results are indicative of a bigh reactivity of boldine towards free radicals. The anaJysis of the boldine effect as I function of incubation times suggests that a rnetabolite resulting from the interaction of boldine with úee radicals also exhibits antioxidant activity, being more efficient than boldine in brain homogenate luto-oxidation and leS5 efticient in Iysozyme protection uperiments. This behavior may,be Bccounted for in terms of the relalÍve Jocation of the scavengers needed to afford maximal protection.
