Chemical composition of the pods of Albizia polyphylla.

ABSTRACT

In this study, we report for the first time the presence of alkaloids belonging to ß-carboline type in the pods of the endemic Albizia polyphylla from Madagascar. Three major alkaloids were isolated and structurally identified as 1-methyl-ß-carboline, (+)-(R)-1-methyl-1,2,3,4-tetrahydro-ß-carboline and (-)-(S)-1,2-dimethyl-1,2,3,4-tetrahydro-ß-carboline.
