Pich. and indigenous to Madagascar, has been shown to contain yohimbine (73), ajmalicine (74), tetrahydroalstonine, and a new base (75) with a j8-anilinoacrylate chromophore, lanceine, C20H26N2O3 or C24H30N2O4, mp 198°, [a]D +64° (EtOH) and +62° (CHCI3). The latter compound, upon lithium aluminum hydride reduction, yielded an indoline that was readily acetylated. [Pg.282]
