EFFECTS OF ANTIOXIDANTS IN PREVENTING THE THERMAL-DECOMPOSITION OF PHOSPHATIDYLCHOLINE HYDROPEROXIDE

Some typical antioxidants, sesamol, alpha-tocopherol, BHT and ascorbic acid, were examined for their effects on preventing the thermal decom position of phosphatidylcholine hydroperoxide (PC-OOH), sesamol alone showing some activity. The others, however, had no significant effect, which is in sharp contrast to our previous studies on their remarkabl e activity toward the thermal decomposition of fatty acid hydroperoxid e. Ascorbic acid, which accelerated the decomposition of fatty acid hy droperoxide, was found to have no effect on PC-OOH in its decompositio n and prevention.
