Abstract:
A process for obtaining triterpene glycosides from a plant source containing triterpene glycosides, comprising the steps of:providing a fresh plant source material containing triterpene glycosides;obtaining a liquid extract from said source material, said liquid extract containing said triterpene glycosides;mixing said liquid extract with a solution saturated with at least one element selected from the group consisting of elements having an oxidation number of two, elements having an oxidation number of one, and combinations thereof so as to provide a mixture;allowing said mixture to rest so as to provide a solid precipitate material and a liquid portion containing soluble portions of said liquid extract including said triterpene glycosides;passing said liquid portion through a column containing a neutral macroporous resin so as to absorb portions of said liquid portion including said triterpene glycosides onto said neutral macroporous resin;rinsing said column with an alcohol so as to obtain an alcohol solution containing said triterpene glycosides;condensing said alcohol solution so as to provide a purified liquid triterpene glycoside solution; anddrying said purified liquid triterpene glycoside solution so as to provide a dry composition containing said triterpene glycosides.
