This is an industrial purification method to purify the fictitious biotoxins of biological activity, such as new saxotoxin, saxotoxin and gonyarra toxin, including: (a) providing some fictitious toxin sources, such as cultivating cyanobacteria clones, wet granulation or crystalloid bacteria； (b) materials extracted from cyanobacteria lysine are frozen and separated in organic and water phases (chloroform mixture: 1:50% methane, 50% acetic acid 1mm, 50% v / V, pH value between 4-5), as acid means to maintain the primary biological activity；(c) using the ambient temperature steam rotor to obtain the previous stage aqueous phase concentrate or grade (a) culture medium； (d) centrifuging the concentrate to obtain a filter； (E) cleaning the spine through a permeable diatomic soil column to obtain scintillation Ethanol solution: water: acido 5mm 2:1:1； (f) optical fiber generated through active carbon column and release erythromycin； (g) erythromycin is released through a sulfur dioxide soil column prefix；(H) dissolving the Eden water of the previous period by evaporating a part of pure red cross and Red Crescent extract from the organic solvent； 1. Preparing the pure red cross and Red Crescent extract by acquiring pure red cross and Red Crescent. These fictional toxins are used in cosmeticsSE REFIERE A UN METODO DE PURIFICACION INDUSTRIAL DE FICOTOXINAS BIOLOGICAMENTE ACTIVAS TALES COMO NEOSAXITOXINA, SAXITOXINA Y GONYAULATOXINA, QUE COMPRENDE: A) PROPORCIONAR UNA CANTIDAD DE UNA FUENTE DE FICOTOXINAS TAL COMO CULTIVO DE UN CLON DE CIANOBACTERIAS, UN PELLET HUMEDO O CONGELADO DE CIANOBACTERIAS, ENTRE OTROS； B) EL MATERIAL PROVENIENTE DE LA LISIS DE CIANOBACTERIAS, SE SOMETE A UNA EXTRACCION EN FRIO Y SEPARACION DE FASES ORGANICA Y ACUOSA (MEZCLA CLOROFORMO:METANOL 1:1 EN 50% Y ACIDO ACETICO 1mM EN 50% V/V CON PH ENTRE 4 Y 5) SIENDO EL MEDIO ACIDO PARA MANTENER LA ACTIVIDAD BIOLOGICA DEL PRINCIPIO ACTIVO； C) OBTENER UN CONCENTRADO DE LA FASE ACUOSA OBTENIDA EN LA ETAPA ANT
