Twelve alkaloids, seven of which are new, have been isolated from the root bark of Strychnos panganensis collected in Tanzania. The novel monoindole alkaloid are A-desacetylspermostrychnine (17), 12-hydroxy-11-methoxy-nor-c-fluorocurarine (18), 12-hydroxy-l l-methoxy-/V-acetyl-nor-C-fluorocurarimine (19) [33]. 

Lastly, beside monoindole, four dimeric indole alkaloids of the reticuline-diaboline type have been isolated from the root bark of Strychnos panganensis two couple of stereoisomers on C-19 or C-19 named panganensine R (30) and S (31), and panganensine X (32) and Y (33) respectively [33]. It has not been possible to assign the C-19 configuration for 32 and 33.
