DETOXIFICATION OF SAPONINS

摘要

Saponin material extracted from plants is purified and made nontoxic to microbial organisms by removing constituents from an aqueous solution of the saponin extract which have an apparent molecular weight of less than about 600 in the aqueous solution. In a preferred embodiment, an aqueous solution of saponin is prepared and then passed through a filter membrane having average pore sizes no smaller than about 11 angstroms in diameter and no larger than about 24 angstroms in diameter while adding amounts of pure aqueous solvent to the solution approximately equal in volume to the liquid passing through the membrane. The toxic material will be in the liquid passed through the membrane.
