Abstract:
An improved method for the removal of polyphenolic compounds from aqueous extracts of plants is presented. The method removes > 99% polyphenolic compounds from 5 mg of extract. The method is simple, robust and reproducible. We examined the removal of polyphenolics from 5 different aqueous extracts of Chinese medicinal herbs.
