Folic Acid Tablets

Action and use

Vitamin B component.

Definition

Folic Acid Tablets contain Folic Acid.

The tablets comply with the requirements stated under Tablets and with the following requirements.

Content of folic acid, C19H19N7O6

90.0  to 110.0% of the stated amount.

Identification

Carry out the method for thin-layer chromatography, Appendix III A, using silica gel G as the coating substance and a mixture of 20  volumes of 13.5m ammonia, 20  volumes of propan-1-ol and 60  volumes of ethanol (96%) as the mobile phase. Apply separately to the plate 2 µl of each of the following solutions. For solution (1) extract a quantity of the powdered tablets containing 0.5  mg of folic acid with 1  ml of a mixture of 1  volume of 13.5m ammonia and 9  volumes of methanol, centrifuge and use the supernatant liquid. Solution (2) contains 0.05% w/v of folic acid EPCRS in a mixture of 2  volumes of 13.5m ammonia and 9  volumes of methanol. After removal of the plate, allow it to dry in air and examine under ultraviolet light (365  nm). The principal spot in the chromatogram obtained with solution (1) is similar in position, fluorescence and size to that in the chromatogram obtained with solution (2).

Tests

Hydrolysis products

Carry out the method for liquid chromatography, Appendix III D, using the following solutions and protecting solutions (1) and (2) from light. Solution (1) is a solution in the mobile phase containing 0.5 µg of 4-aminobenzoic acid and 2.0 µg of N-(4-aminobenzoyl)-l-glutamic acid per ml. For solution (2) shake a quantity of the powdered tablets containing 5.0  mg of folic acid with 50  ml of the mobile phase, centrifuge and use the supernatant liquid.


The chromatographic procedure may be carried out using (a) a stainless steel column (20  cm × 4.6  mm) packed with octadecylsilyl silica gel for chromatography (10 µm) (Spherisorb ODS 1 is suitable), (b) 0.05m potassium dihydrogen orthophosphate, adjusted to pH 5.5 with 5m sodium hydroxide, as the mobile phase with a flow rate of 2  ml per minute and (c) a detection wavelength of 269  nm.


In the chromatogram obtained with solution (1) two peaks, due to N-(4-aminobenzoyl)-l-glutamic acid and 4-aminobenzoic acid, are obtained in order of their emergence. The test is not valid unless the resolution factor between the two peaks is at least 3.


The areas of the peaks due to 4-aminobenzoic acid and N-(4-aminobenzoyl)-l-glutamic acid in the chromatogram obtained with solution (1) are greater than the areas of any corresponding peaks in the chromatogram obtained with solution (2).


Uniformity of content

Tablets containing less than 2  mg of folic acid comply with the requirements stated under Tablets using the following method of analysis. Carry out the method for liquid chromatography, Appendix III D, using the following solutions. For solution (1) add 1  ml of 0.5m hydrochloric acid to 5  ml of a 0.0020% w/v solution of folic acid EPCRS in 0.1m sodium hydroxide and dilute to 10  ml with the mobile phase. For solution (2) shake one tablet with 5  ml of 0.1m sodium hydroxide, add sufficient mobile phase to produce a solution containing 0.001% w/v of folic acid, centrifuge and use the supernatant liquid.


The chromatographic procedure may be carried out using (a) a stainless steel column (20  cm × 4.6  mm) packed with octadecylsilyl silica gel for chromatography (10 µm) (Spherisorb ODS 1 is suitable), (b) a mixture of 93  volumes of 0.05m potassium dihydrogen orthophosphate and 7  volumes of acetonitrile adjusted to pH 6.0 with 5m sodium hydroxide as the mobile phase with a flow rate of 2  ml per minute and (c) a detection wavelength of 283  nm.


Calculate the content of C19H19N7O6 in each tablet using the declared content of C19H19N7O6 in folic acid EPCRS.

Assay

For tablets containing 2  mg or more of folic acid

Weigh and powder 20  tablets. Carry out the method for liquid chromatography, Appendix III D, using the following solutions, protected from light. For solution (1) dilute 5  ml of a 0.020% w/v solution of folic acid EPCRS in 0.1m sodium hydroxide to 100  ml with the mobile phase. For solution (2) shake a quantity of the powdered tablets containing 20  mg of folic acid with 50  ml of 0.1m sodium hydroxide, dilute to 100  ml with the same solvent, centrifuge and dilute 5  ml of the supernatant liquid to 100  ml with the mobile phase.


The chromatographic procedure described under Uniformity of content may be used.


Calculate the content of C19H19N7O6 in the tablets using the declared content of C19H19N7O6 in folic acid EPCRS.


For tablets containing less than 2  mg of folic acid

Use the average of the 10 individual results obtained in the test for Uniformity of content.

Storage

Folic Acid Tablets should be protected from light.
