From the root bark of the apocynacea Hedranthera barteri ( Hook. f. ) Pichon were isolated the known indole alkaloids vobtusine ( 1 ), voacamine ( 2 ), callichiline ( 3 ), voacangine ( 4 ) and conoflorine ( 5 ), as well as the unknown plant bases amataine, goziline and owerreine, and also beninine and 1, 2‐dehydrobeninine. The structures of the two last mentioned alkaloids were shown in an earlier publication to be 6 and 7 , respectively. Amataine, goziline and owerreine are bis‐indole alkaloids, which on the basis of their chemical and spectroscopic (especially mass spectroscopic) properties have been assigned the structures 8 , 9 and 10 , respectively.
