Abstract
TAA (transaconitic acid) may be extracted from plants with acidified boiling water or with ethyl alcohol under reflux, but the water extraction is preferred. Although TAA could be adsorbed completely on anion-exchange resins, its subsequent elution is rather difficult and, therefore, the use of anion exchange resins in the process of purification is not recommended. A procedure suitable for the extraction of TAA is suggested to run as follows: the acid should be extracted from the plant with acidified water, then converted to the free form by passing through a cation exchange resin, and finally extracted by ether using a liquid/liquid extractor.
