Four new alkaloids of the aspidofractinine-type, viz., 11-hydroxykopsingine, 11-methoxykopsingine, 11-methoxy-12-hydroxy-kopsinol and 14,15-beta-epoxykopsingine, were isolated from the leaf extract of Kopsia teoi.

Two new indole alkaloids, kopsidines C and D, in addition to kopsidines A and B, were obtained from the leaf extract of Kopsia teoi. The structures of the new alkaloids were established by spectral methods.

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 lonicerine (2). The two new alkaloids, 16-e...
