Abstract
The amt. of folic acid in whole blood and plasma of various species has been detd. before and after enzymatic digestion with the use of Streptococcus faecal is as the test organism. The amt. of apparent free folic acid in whole blood for the human, chicken, turkey, horse, pig and cattle averaged 0.85, 8.7, 16.8, 3.3, 6.6 and 1.9 my/ml. respectively. The amt. in plasma also varied with different spp. A marked increase in the folic acid content of whole blood and plasma was observed after incubation at 37[degree]C for 46-18 hrs. with takadiastase. From 20-40 m[gamma]/ml. of folic ;acid was found after this treatment.Keywords
