Abstract
Five new proanthocyanidins have been isolated from the roots ofClementsia semenovii A. Bor. The structures of two of these compounds have been established by various chemical and physical methods: 7-0-[6-0-galloyl-β-D-Glcp\(\xrightarrow{6}\)0-β-D-Glcp\(\xrightarrow{6}\)0-βD-Glcp\(\xrightarrow{6}\)0-β-D-Glcp ]-(+)-gallocatechin-(4a-8)-(+)-gallo-catechin-(4a-8)-(-)-epigallocatechin-(4β-8)-(-)-epigallocatechin-(4β-8)-(-) -epigalloactechin-(4β-8)-(+)-catechin - CS-1 and 3-0-galloyl-7-0-(β-D-Glcp\(\xrightarrow{6}\)0-B-D-Glcp)-(-)-epigallocatechin-(4β-8)-[3-0-galloyl-(-)-epigallocatechin]-(4β-8)-[3-0-galloyl-5-0-(6-0-galloyl-0-β-D-Glcp)]-(-)-epicatechin - CS-2.
