Abstract

Process for obtaining the compound methyl (3a-ethyl-3a, 4,6,11,12,13a-hexahydro-1H-indozolino (8,1-cd) carbazole-5-carboxylate) from plants of the genus of the voacanga, characterized by essentially consisting of the following phases: (a) harvesting the seed of the voacanga plant, releasing the seeds of foreign bodies, and crushing the resulting seeds to powder; (b) partial extraction of the alkaloid from the ground seeds obtained in the previous step with a first solvent selected from the group containing petroleum ether and carbon tetrachloride, and separation of this first solvent from the powder thus treated; (c) a second partial extraction of the alkaloid from the seed powder separated and treated according to the preceding step with a second solvent containing ethyl ether, and separation of said second solvent from the seed powder thus treated; (d) a third extraction of the seed powder separated and treated according to the previous step with a third solvent composed of ethanol containing approximately between 1 and 5% acid, and separation of said third solvent from the seed powder thus treated; (d) purification of the acidic ethanol third solvent after removal of the powder in the previous step by elimination of the ethanol and filtration, followed by washing with an immiscible organic solvent, then alkaline the separated aqueous phase and removing the water therefrom for provide the desired dry product.
