摘要：

Two new alkaloids of the aspidofractinine type, viz. kopsinginine and 17-alpha-hydroxy-DELTA14,15-kopsinine, in addition to kopsingine and kopsaporine have been isolated from the bark of Kopsia teoi. The structures of the alkaloids were assigned by thorough analysis of their NMR spectra. The structure of kopsingine was also confirmed by X-ray diffraction analysis.
