Abstrakt: 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-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp)-(+)-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-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp $$\xrightarrow{6}$$ O-β- D-Gl cp-(+)-gallocatechin-(4α—8)-[(+)-catechin-(4α—8)-(3-O-galloyl-(−)-epigallocatechin]2-(4β—8)-(−)-epicatechin.
