<p>A process for producing pyridoxine-5’-α-glucoside by glucosylating pyridoxine at the 5’-position which involves the step of treating pyridoxine or its salt with microbial cells capable of selectively glucosylating pyridoxine at the 5’-position to thereby form pyridoxine-5’-α-glucoside, a culture thereof or processed cells thereof; and a process for producing pyridoxine-5’-α-glucoside by treating pyridoxine or its salt with a glucosylating enzyme, characterized in that the treatment is carried out in the presence of boric acid and/or a boric acid salt to thereby enhance the selectivity of the glucosylation at the 5’-position. According to these methods, pyridoxine-5’-α-glucoside can be easily and effectively produced from pyridoxine or its salt.</p> |
