Abstract

Process of purification of ellagic acid consisting of: placing the raw ellagic acid in aqueous suspension - in adjusting the ph of this suspension between approximately 7.5 and 12 by the addition of fatty amine - in making the indicated suspension crystallize - in collecting by filtration the crystallization - in washing the crystallized reference with an aqueous solution, said concentration amine corresponding to washing waters of ph comprised between approximately 7.5 and 12 - in draining said crystallized - in situating this crystallized in suspension in the water - in situating the ph of this suspension between approximately 6 and 1 by the addition of a strong acid - in filtering the separated solid ellagic acid - in washing this ellagic acid with water until the filtrate is neutralized, and in draining and then drying the acid purified ellagic obtained in this way.
