Title:
植物からのシアル酸含有化合物の抽出法
Document Type and Number:
Japanese Patent JP4682377
Kind Code:
B2
Abstract:
An obj ect of the present invention is to provide an inexpensive and simple extraction method for a sialic acid-containing compound from a raw material which is easily available and has no risk of contamination with pathogens affecting animals (raw material which has high safety) without requiring the use of a reagent harmful to the human body and environment. The present invention is also aimed at providing an extraction method for a sialic acid-containing compound, the method comprising: crudely extracting a soluble component from a plant body (in particular, seeds of cereal and/or seeds of bean) or a processed product of the plant body with water, an alcohol, or an aqueous alcohol; and separating and recovering the sialic acid-containing compound from the resultant crude extract solution by dialysis, salt precipitation, or column chromatography.
