Properties of pyridoxine glucoside.
Intact pyridoxine glucoside showed about 20% of microbiological activity of equivalent mole of pyridoxine for Saccharomyces carlsbergensis 4228 ATCC 9080. The activity was gradually increased accompanied with the prolonged incubation. It seems that pyridoxine glucoside is hydrolyzed to pyridoxine and glucose by a-glucosidase of Saccharomyces carlsbergensis 4228 ATCC 9080 and can be bioassayed a...
متن کاملA tetrahydroisoquinoline-monoterpene glucoside and an iridoid glucoside from Alangium kurzii.
From the leaves of Alangium kurzii, a new tetrahydroisoquinoline-monoterpene glucoside, 6-O-methyl-N-deacetylipecosidic acid and a new iridoid glucoside, 10-O-benzoyladoxosidic acid, were isolated along with alangiside, demethylalangiside, 6''-O-beta-D-glucosylhenryoside, uridine and four known flavonoid glycosides. The structures of new glucosides were determined on the basis of spectroscopic ...
متن کاملStudies of mammalian glucoside conjugation.
The mammalian glucoside-conjugation pathway was studied by using p-nitrophenol as the model substrate and mouse liver microsomal preparations as the source of enzyme. The microsomal preparations supplemented with UDP-glucose glucosylated p-nitrophenol; p-nitrophenyl glucoside was identified by chromatography in six solvent systems. The unsolubilized glucosyltransferase of fresh microsomal prepa...
متن کاملSecondary metabolites in durian seeds: oligomeric proanthocyanidins.
Ethanolic extract of durian seeds was fractionated by reverse phase flash column chromatography and the fractions characterized by electrospray ionization mass spectroscopy. Among a few unknown compounds collected, oligomeric proanthocyanidins (OPCs) were found to be one of the main compounds. Based on this result, the OPCs were purified the first time from the durian seeds using standard proce...
متن کاملProanthocyanidins: Biological Activities Associated with Human Health
Proanthocyanidins, also called condensed tannins, are oligomers and polymers of monomeric flavans linked through specific single (B linkages) and double (A linkages) bonds. These secondary plant metabolites have substantial antioxidant activity. They are prevalent in some foods and dietary supplements including several berries, red grapes and their wines, and seeds, baking chocolate, cinnamon, ...
