The chemical synthesis of pyridoxine-5'-beta-D-glucoside (5'-beta-PNG) was investigated using various glucoside donors and promoters. Hereby, the combination of alpha 4,3-O-isopropylidene pyridoxine, glucose vested with different leaving and protecting groups and the application of stoichiometric ...
and a process for producing pyridoxine-5'-&agr -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 ...
The behaviors of the isolate on thin-layer and Aminex A5 column chromatograms were coincident with those of synthetic pyridoxine--d-glucoside which was obtained by Knigs-Knorr condensation of 卤4,3-O-isopropylidene pyridoxine and 2,3,4,6-tetra-O-acetyl-卤-d-glucopyranosyl bromide. On acid ...
4′-O-methylpyridoxine (MPN) and its 5′-glucoside (MPNG) in Ginkgo biloba seeds cause poisoning. Sample preparation for high-performance liquid chromatography was optimized to determine the amounts of MPN and MPNG at various extraction temperatures and pH levels. The effects of heating ...
