Two new epimeric pairs of iridoid scyphiphin A₁ (1a), A₂ (1b) and scyphiphin B₁ (2a), B₂ (2b) were isolated from Scyphiphora hydrophyllacea Gaertn. F. Their structures were elucidated by spectroscopic methods. The mixture of scyphiphin B₁ and scyphiphin B₂ showed moderate cytotoxicity against human hepatoma SMMC-7721 cell line in vitro by MTT method.
