摘要

1. The use of at least one oxime derivative of 3,5-seco-4-norcholestane, or one of its addition salts with acceptable acids, or one of its esters, or one of its addition salts with the indicated esters of acceptable acids as antioxidant. ! 2. The use according to claim 1 of at least one oxime derivative of 3,5-seco-4-norcholestane, corresponding to the formula I! ! wherein: ! - X and Y taken together form an oxime radical (= NOH), or X is hydroxyl and Y is a hydrogen atom; ! - B is hydroxyl, and C and D, identical or different, are a hydrogen atom, or an alkyl radical, linear or branched, containing from 1 to 4 carbon atoms; or ! - B and C, taken together, represent a keto group, and B represents methyl, hydroxyl or methylamine; or ! - B and C represent a hydrogen atom, and D represents a methylamino group; or ! - B and C, taken together, represent an oxime group, and D represents methyl; and! - R is an alkyl radical, linear or branched, containing from 1 to 10 carbon atoms. ! 3.
