FIELD: medicine.
SUBSTANCE: invention describes a method for lipoic acid measurement in biologically active additives by cathode voltammetry involving transferring a substance from a sample into a solution and taking voltammetric measurement; the cathode voltammetry is performed on a mercury-film electrode at potential -0.373 V of a relatively saturated silver-chloride electrode with borate buffer solution pH 9.18 at continuously current potential trace at 0.06 V/s with the determined lipoic acid content range from 4.5·106 to 1.1·10-3 mole/l.
EFFECT: improving sensitivity and expressivity of the method for measuring lipoic acid in tabletted BAAs by cathode voltammetry.
