Abstract: The invention relates to spheroids which are obtained using a method comprising the following steps consisting in: supplying an active principle of vegetable origin in an isolated form; supplying a solution of vegetable origin, containing the active principle or a precursor thereof; supplying an absorbing and adsorbing substance having plastic properties that are compatible with the method; mixing said different products and wetting the mixture with a wetting liquid; extruding the wet mixture; and forming spheroids through the spheronization of the extruded product. The invention also relates to sample applications such as artesunate-based antimalarial spheroids and aspring-based spheroids.

Abstract: Compositions of natural, especially plant, constituents in the form of spheroids in particular of the medicinal type and formulations necessary to their preparation by a technical extrusion and spheronization system. Compositions characterized by the direct use of large quantities of solutions of natural, especially plant, origin such as liquid extracts adsorbed by natural or synthetic polymer-type substances. These various components are selected so that their combination permits the obtainment of a mass of a plasticity compatible with the technical extrusion and spheronization system. According to the process, liquid extract is prepared, this extract is incorporated in a substance of a polymeric type, the correctly moistened mass is extruded by micro-extrusion techniques and the extrudates are spheronized and then dried and calibrated.
