A new HPTLC method has been developed for identification and quantification of folic acid, N -[4-{[(2-amino-4-hydroxy-6-pteridynyl)methyl]amine}benzoyl]glutamic acid, a water-soluble vitamin. Identification and quantification were studied with different mobile phases. The best results were obtained on HPTLC silica gel 60 F 254 plates (Merck) with iso -propanol-ethyl acetate-water-ammonia, 4 + 2 + 2 + 1, as mobile phase. Quantification was achieved by use of densitometry at λ = 280 nm, using the deuterium lamp. Recovery, linearity, reproducibility, and accuracy were excellent for all the samples studied. The method has been applied successfully for the identification and quantification of folic acid in different pharmaceutical dosage preparations. The standard and assay preparations are stable for up to 48 h.
