Se adicionaron 10 mL de CHCl3, recuperando la fase cloroformica, este proceso se repitio hasta extraer todos los alcaloides desde la fase acuosa hacia el extracto cloroformico, para esto se realizaron evaluaciones en la fase cloroformica mediante cromatografia en capa fina y con el reactivo de Dragendorff.
