Title: Indole alkaloids as systematic markers of the Apocynaceae
Abstract: Indole alkaloids can be characterized by skeletal specialization (S), determined upon consideration of their relative position on a biogenetic map and the number of their naturally occurring substitutional derivatives, as well as by oxidation level (O). The mean (S) and (O) for contained alkaloids of a given plant taxon are taken to represent evolutionary advancement parameters, respectively EAs and EAo.A correlation of these EAs/EAo values for tribes of the Apocynaceae-Plumerioideae reveals a chemical gradient, given by gradually increasing EAs and EAo values, to link Carisseae-Alstonieae-Rauvolfieae-Tabernaemontaneae.
