Abstract
Following the characterization of thiohemiaminal type nuphar alkaloids with immunosuppressive activity, four new thiaspirane sulfoxide type dimeric sesquiterpene alkaloids, nupharpumilamines A, B, C, and D, wer e isolated from Chinese Nupharis Rhizoma, the dried rhizoma of Nuphar pumilum (TIMM.) DC. The structures of nupharpumilamines A, B, C, and D were determined on the basis of chemical and physicochemical evidence .
