Title:
METHOD OF PURIFYING SHIKIMIC ACID
Document Type and Number:
WIPO Patent Application WO/2001/068891
Kind Code:
A1
Abstract:
A method of purifying shikimic acid characterized by treating a shikimic acid-containing solution with an alkali, adsorbing shikimic acid by an anion exchange resin and then eluting it. As the anion exchange resin, it is preferable to use a strongly basic resin. As the eluent, it is preferable to use a strongly alkaline aqueous solution, in particular, an aqueous NaOH solution. By using this method, shikimic acid can be efficiently separated from analogous compounds such as dehydroshikimic acid having a similar chemical structure.
