Five new proanthocyanidins have been isolated from the roots of Clementsia 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 →6 O-βD-Glcp →6O-β-D-Glcp → 6O-β-D-Glcp]-(+)-gallocatechin-(4α-8)-(+)-gallocatechin- (4α-8)-(-)-epigallocatechin-(4β-8)-(-)-epigallocatechin-(4β-8)- (-) -epigallocatechin-(4β-8)-(+)-catechin - CS-1 and 3-O-galloyl-7-O-(β-D-Glcp → 6O-β-D-Glcp)-(-)-epigallocatechin-(4β-8)-[3-O-galloyl-(-)- epigallocatechin]-(4β-8)-[3-O-galloyl-(-)-epigallocatechin]-(4β-8)-[3- O-galloyl-5-O-(6-O-galloyl-O-β-D-Glcp)]-(-)-epicatechin - CS-2.
