Abstract
The folate pattern in cabbage was studied by chromatography on Sephadex G-25 and DEAE-cellulose columns associated with markers of high specific radioactivity and with differential microbiological assay. More than 90% of cabbage folate is polyglutamates containing more than five glutamic acid residues, mainly as the 5-methyl derivatives. The distribution is as follows: 52% of total cabbage folate is 5-CH3-H4PteGlu7, 32% is 5-CH3-H4PteGluc6, 7% is 5-CH3-H4PteGlu8, 4% is 5-CHO-H4PteGlu7, and the rest is 5-CH3-H4PteGlu3–5.Keywords
