Science, 1959
Various purification procedures for folic acid were investigated. The criteria of purity were a negative Bratton-Marshall test and the absence of fluorescent spots on paper chromatograms. Since no method provided a pure product, a procedure consisting of cellulose column chromatography followed by filtration through charcoal was developed.

Folic acid and psychopathology
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 19891. The incidence of folic acid deficiency is high in patients with various psychiatric disorders including depression, dementia and schizophrenia. 2. In epileptics on anticonvulsants, folate deficiency often occurs because anticonvulsants inhibit folate absorption. In these patients folate deficiency is often associated with psychiatric symptoms. 3. In

Psychiatry and Clinical Neurosciences, 1977
SUMMARYWith 15 cases of epilepsy as the subject, studies were made of the therapeutic effects of folic acid on psychiatric symptoms and clinical seizures. Folic acid proved effective for a part of chronic and prolonged psychiatric symptoms shown by epileptic patients and brought on slight improvement in hyperexcitability, aggressiveness, bad humor and ...

Three cases of folic acid deficient megaloblastic anaemia are described in which a combined oral contraceptive has been aetiologically implicated. The first patient proved to have coeliac disease precipitated clinically by administration of the oral contraceptive. Case 2 had a long standing marginally folate deficient diet and became anaemic only after

Photogenotoxicity of folic acid
Free Radical Biology and Medicine, 2013Folic acid (FA), also named vitamin B9, is an essential cofactor for the synthesis of DNA bases and other biomolecules after bioactivation by dihydrofolate reductase (DHFR). FA is photoreactive and has been shown to generate DNA modifications when irradiated with UVA (360 nm) in the presence of DNA under cell-free conditions.
