Abstract

Glycosylation of phenolic hydroxyl groups of serotonin and epinephrine, using an amyloglucosidase from Rhizopus mold was carried out with D-glucose, D-galactose, D-mannose and D-ribose in di-isopropyl ether solvent to yield 13-29% of glycosides in 48h. NMR spectroscopic data indicated that the reaction occurred between the phenolic -OH group of serotonin and C1α /β and / or 6-O-groups of D-glucose, D-galactose, D-mannose and D-ribose. In case of epinephrine, 4 –OH and 3 –OH groups reacted with C1 β anomer of D-glucose and C-1 α/β anomers of D-mannose.
