Galloylsucroses from rhubarbs

Abstract Chinese rhubarb yielded a new class of gallotannins having a sucrose core, while North Korean rhubarb was found to contain four gallotannins. On the basis of chemical and spectroscopic evidence, the structures of the gallotannins were established as 6′-O-,4′-O-, 6-O-, 1′-O- and 2-O-monogalloylsucrose, respectively.
