Isolamento biomonitorado de alcalóides tóxicos de Prosopis juliflora (algaroba)

Abstract

A phytochemical investigation of the pods of Prosopis juliflora cultivated in the semi arid region of the State of Paraiba, monitored by pharmacological tests, led to the isolation, purification and identification of its main alkaloid - juliprosopine. The presence of other compounds such as juliprosine and juliprosinene, was observed through analysis of 13C NMR. This work suggests that the toxic activity, observed in laboratory animals, is chemicaly related with the piperidine alkaloids present in the pods of this Leguminosae.
