Laboratory-scale experiments were conducted with the goal of releasing ferulic acid (FA) and p-coumaric acids (p-CA) from the solid residue obtained after prehydrolysis of prunings of vine shoots. Firstly, an alkaline hydrolysis with different hydroxides at mild conditions of temperature (35 ◦C) was performed, followed by acidification of liquors, and liquid–liquid extraction with ethyl acetate.

Abstract
Laboratory-scale experiments were conducted with the goal of releasing ferulic acid (FA) and p-coumaric acids (p-CA) from the solid residue obtained after prehydrolysis of prunings of vine shoots. Firstly, an alkaline hydrolysis with different hydroxides at mild conditions of temperature (35 ◦C) was performed, followed by acidification of liquors, and liquid–liquid extraction with ethyl acetate.
