PURPOSE:To obtain the titled substance useful for foods and drinks, cosmetic, etc. in high purity inexpensively, by adsorbing an extract of bark of Quillaia Saponaria Mol containing quillaia saponin, a surface active substance, on adsorption resin of synthetic high polymer, followed by desorbing it. CONSTITUTION:An aqueous solution of an extract of bark of quillaia saponin, a surface active substance, existing in the bark of Quillaia Saponaria Mol is brought into contact with an adsorption resin of synthetic high polymer having macro network structure preferably by column method, so that the surface active substance is adsorbed on the resin. The adsorbed surface active substance is desorbed with a hydrophilic organic solvent or a mixture of it and water to give a desorbed solution, from which the surface active substance is recovered. |
