Free folate (monoglutamate forms) and total folate (monoglutamate+polyglutamate forms) are differentiated. Vegetables contained 27–187 μg/100 g and fruits 10–80 μg/100 g total folate. The free folate portion ranged from 6.3% to 96.8% (mean 35%) in vegetables and from 11.6% to 89.0% (mean 56%) in fruits. In addition, the results of the quantification of the main folate derivatives tetrahydrofolic acid (THF), 5-methyltetrahydrofolic acid (5-CH 3 -THF) and 5-formyltetrahydrofolic acid (5-CHO-THF) are presented. The mean values were 70% 5-CH 3 -THF, 20% 5-CHO-THF and 10% THF. Their total, resulting from the addition of pteroylglutamate equivalences, is comparable with the results of microbiological methods reported in the tables of nutritive values.
