Alcalóides de Duguetia trunciflora Maas (Annonaceae)

Abstract

The genus Hornschuchia obliqua belonging to the Annonaceae family. The family comprising ca 130 genera and 2300 species, located in the Magnoliales, a primitive order of plants, is known to produce isoquinoline alkaloids derivatives 1. Indeed the great majority of alkaloidal constituents of these plants are isoquinoline-derived structures, along with a wide range of non-alkaloidal compounds of varied stuctural types 2,3. The present paper describes the chemical investigation of the alkaloids from Hornschuchia obliqua, isolated until now.
