Five further alkaloids, des-N'a-methylanhydromacralstonine, quebrachidine, vinervinine, pleiocarpamine, and 2,7-dihydropleiocarpamine, have been isolated from Alstonia muelleriana bark. Phytochemical problems in the genus Alstonia are considered, especially with reference to the `macroline-derived' indole and bis-indole alkaloids.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33878/1/0000139.pd
