  • Method for recovering indicine-N-oxide
    Patent number: 4458082
    Abstract: An improved process for recovering Indicine-N-oxide from plant sources which involves water extracting the plant material, preferably by water buffered at pH 7, followed by adsorbing the Indicine-N-oxide from the extract, after which the Indicine-N-oxide is eluted from the adsorbent in alcoholic solution, then concentrated and purified as heretofore.Desirably, the adsorbed Indicine-N-oxide is water washed prior to elution so as to remove any water soluble impurities that had been adsorbed from the extract.A preferred adsorbent is a cross linked polystyrene.
