Six monomeric indole alkaloids have been isolated and identified from
the stem bark and leaves of Kopsia teoi collected in Malaysia, Four of
them are known: kopsingine [1], isoeburnamine, rhazinilam, and lonice
rine [2]. The Two new alkaloids, 16-epi-17-alpha-hydroxy-Delta(14,15)-
kopsinine [3] and 11,1 2-methylenedioxykopsaporine [4], belong to the
same aspidofractinine group.
