  The structures of proanthocyanidins CS-3 and CS-4, isolated from the roots of Clementsia semenovii have been established on the basis of chemical and spectral studies. CS-3 is 7-O-(6-O-galloyl-β-D-Glcp→6O-β-D-Glcp→6O-β-D-Glcp→6O-β-D-Glcp→6O-β-D-Glcp)-(+)-catechin-(4α-8)-(−)-epigallocatechin-(4β-8)-(+)-catechin-(4α-8)-(−)-epigaLLocatechin-(4β-8)-(−)-epigallocatechin-(4β-8)-(−)-epigallocatechin, and CS-4 is 3-O-galloyl-7-O-[6-O-galloyl-β-D-Glcp→6O-β-D-Glcp→6O-β-D-Glcp-(+)-gallocatechin-(4α-8)-[(+)-catechin-(4α-8)-(3-O-galloyl-(−)-epigallocatechin]2-(4β-8)-(−)-epicatechin.
