Four new flavanone oligoglycosides, theaflavanosides I, II, III, and IV, were isolated from the seeds of Camellia sinensis. The structures of theaflavanosides were elucidated on the basis of chemical and physicochemical evidence. Among them, theaflavanoside III was found to show hepatoprotective effect on D-galactosamine-induced cytotoxicity in primary cultured mouse hepatocytes.
