title: [Evolution of tocopherols in relation of unsaturated fatty acids during maturation of seeds of rapeseed (Brassica napus L.)].
abstract: The oil content increases during the maturation of seeds (rise of 30%), but decreases at the end of seed maturation. Differences between SDS-PAGE total protein profiles were shown. Polyunsaturated fatty acids contents increase during middle-maturation. Contents of alpha and gamma tocopherols increase with time. This increase is explained by the fact that tocopherols participate actively in the protection of membranes whose phospholipids consist of polyunsaturated fatty acids (PUFAs).
