Abstract
Process for obtaining isovaleric acid esters that act as sedatives and spasmolytics, from the roots and rhizomes of valerian species containing esters of isovaleric acid, by extraction by a lipophilic solvent, characterized in that the roots or rhizomes shredded or sprayed, they are extracted at a temperature below 30º C by means of a lipophilic solvent in the presence of substances that act as acids or only by means of the substances that act as acid, possibly together with the corresponding alkali or ammonium salts as a buffer solution, in a weakly acid pH field.
