ALCALOIDES DE SOPHORA TETRAPTERA, SENSU REICHE. 1. AISLAMIENTO DE CITISINA, METILCITISINA y MATRINA DE LAS SEMILLAS

Abstract

Sophora tetraptera, sensu R,eiche, is the scientific name assigned to a southem Chilean tree known by the names pelú and pilopilo, which closely resembles the New Zealand species S. tetraptera J. Mill. and S. microphylla Ait. from a morphological viewpoint. A preliminalj' study of the seed alkaloids of this Chilean plant yielded cytisine, methylcytisine, and matrine in a ratio which supports the taxonomic segregation of the pelú from the species native to New Zealand.
