Abstract

Procédé d'estérification d'un extrait oligomère polyphénolique d'origine végétale par action d'un chlorure d'acide, caractérisé par le fait que l'on place ledit extrait dans un milieu liquide non solvant pour ledit extrait mais solvant pour le(s) ester(s) à obtenir, de façon à obtenir une suspension; que l'on ajoute à ladite suspension au moins une amine tertiaire aliphatique à bas point d'ébullition en présence d'une quantité catalytique d'au moins une base organique autre que la pyridine; et que l'on introduit dans ce mélange au moins un chlorure d'acide gras, le mélange réactionnel étant agité à une température inférieure à 40.degree.C puis concentré par évaporation pour obtenir un extrait estérifié. L'invention a également pour objet les compositions obtenues par ce procédé et leur utilisation en thérapie humaine ou en cosmétique.
