Abstract: A novel alkaloid, named hypodematine, was isolated from the whole plant of a fern.Htpodematium sinemse lwatsuki.Its structure has been elucidated to have a novel skeleton of benzo-azacyclooctatetraene with a phenyl substituent by means of 1H-1H COSY. 1H-13C COSY.and long-range 1H-13C COSY spectroscopy.

Key words: Hypodematium sinense, Hypodematine, 2D-NMR
