[Pteroylglutamate derivatives in seedlings of Brassica napus oleifera].
The pteroylglutamate derivatives in Colza seedlings (Brassica napus) have been separated by chromatography on DEAE cellulose and determined by differential microbiological assay. A marked activity of formyl derivatives is confirmed by use of labelled folic acid, and the presence of several conjugated folates is shown.
