Abstract
The present invention discloses a method for purifying oxidized form of β-nicotinamide adenine dinucleotide, comprising the steps of: sequentially microfiltrating and nanofiltrating a reaction solution obtained after an enzymatic reaction by using filteration membranes, to collect a concentrate for use; then adding an acid to the concentrated filtrate, to adjust the pH of the concentrate, and purifying by gradient elution using a reverse-phase chromatographic column as a stationary phase, a buffer solution as a phase A, and ethanol as a phase B; and concentrating the purified solution by nanofiltrating it with a filtration membrance, and then freeze drying it in a vacuum freeze drier. In the present invention, the oxidized form of β-nicotinamide adenine dinucleotide is purified by reverse phase high performance liquid chromatography, such that the oxidized form of β-nicotinamide adenine dinucleotide has a high purity and high yield, thus meeting the requirements in industry.
