  • Publication number: 20140030318
    Abstract: The present disclosure concerns methods for producing purified saponins, such as QS-21, which reduces the number of necessary lyophilization cycles to one by a step of solvent exchange and optional subsequent exposure of the purified saponin product to at least one exposure to dry gas followed by exposure to a vacuum to further rid the purified saponin product of residual solvent molecules.
