Received Date: 5 April 1990

An alkaloid with a novel structure, named Hypodematine, was isolated from Hypodematium sinense Iwatsuki(belonging to Thelypterdaceae)⁽¹⁾.Its structure was elucidated by means of the ¹H-¹H COSY' ¹H-¹³C COSY and long-range ¹H-¹³C COSY spectroscopy to have the skeleton of benzo-aza-cyclooctatetraene with a phenyl substituent.Such basic structure has not been found in the na-tural product before.
