Synthesis of gallotannins [PDF]
Carbohydrate Research, 2001 As a contribution to the synthesis of gallotannins, four O-galloyl-D-glucoses (3-O-, 6-O-, 3,6-di-O-, 3,4,6-tri-O-galloyl-D-glucose) have been prepared by the reaction of tri-O-benzylgalloyl chloride and partially protected glucose derivatives (1,2-O-, and 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose), followed successively by catalytic ...

Biodegradation of gallotannins and ellagitannins [PDF]
Journal of Basic Microbiology, 2006 AbstractNowadays, many researches have been made on gallotannin biodegradation and have gained great success in further utilization. Some of industrial applications of these findings are in the production of tannase, the biotransformation of tannic acid to gallic acid or pyrogallol and detannification of food and fodder. Although ellagitannins have the
