Abstract

PROCEDIMIENTO DE OBTENCION DE UN EXTRACTO ESENCIALMENTE COMPUESTO DE GINKGOFLAVONOIDES A PARTIR DE HOJAS DE GINKGO BILOBA. EL PROCEDIMIENTO EXTRAE LAS HOJAS DE GINKGO BILOBA CON SOLUCIONES ACUOSAS DE CETONAS O ALCOHOLES INFERIORES, CON ELIMINACION DEL DISOLVENTE ORGANICO HASTA OBTENCION DE UN EXTRACTO BLANDO. ESTE EXTRACTO SE DISUELVE EN UNA MEZCLA DE AGUA CON UN DISOLVENTE ORGANICO LIMITADAMENTE SOLUBLE EN AGUA Y SE EXTRAE CON EL MISMO SOLVENTE ORGANICO SATURADO EN AGUA. LA CONCENTRACION DE LA FASE ORGANICA CONDUCE A UN EXTRACTO BLANDO DEL QUE EVENTUALMENTE SE ELIMINA LOS COMPONENTES LIPOIDES. EL EXTRACTO PUEDE EVENTUALMENTE SER TRATADO CON UN ALCOHOL INFERIOR, FILTRADO Y CONCENTRADO. EL TRATAMIENTO CON SOLUCION ACUOSA DE SULFATO AMONICO JUNTAMENTE CON DISOLVENTE ORGANICO COMPUESTO POR UN ALCOHOL INFERIOR Y UNA CETONA INFERIOR; CONDUCE A UNA FASE ORGANICA QUE CONTIENE EL PRODUCTO. EL EXTRACTO SECO FINAL POR EVAPORACION DEL DISOLVENTE ORGANICO CONSTA ESENCIALMENTE DE GINKGOFLAVONOIDES EN UN15-40%, CONTENIDO MAXIMO DE 1,5% DE PRODELFINIDINAS Y UN 10% DE PROANTOACINIDINAS. ESTE EXTRACTO SE USA PARA LA TERAPEUTICA Y PROFILAXIS DE CIRCULACION CEREBRAL DEFICITARIA Y PARA PREPARACIONES TOPICAS COSMETICAS.
