Abstract

Un método para separar selectivamente los glucosidos esteroides deseables de componentes indeseables presentes en un material de planta de la familia de las Asclepiadáceas que los contienen. El método comprende poner en contacto el material de planta o material derivado de las plantas (en esta descripcion: ôel materialö) con líquido o dioxido de carbono supercrítico bajo condiciones en donde los glucosidos esteroides deseables se disuelven en el líquido o dioxido de carbono supercrítico de preferencia que los componentes indeseados, y subsecuentemente recuperar los glucosidos esteroides deseables de la solucion de dioxido de carbono. Reivindicacion 2: Un método de acuerdo con la reivindicacion 1, caracterizado porque son extractados predominantemente los ácidos grasos y otros materiales lípidos en una primera extraccion utilizando dioxido de carbono líquido y una primera presion, seguido de la extraccion de glucosidos esteroides usando dioxido de carbono supercrítico a una segundo presion, en tanto que, se dejan los glucosidos esteroides no deseados u otros compuestos en la matriz de la planta.
