From Plant Bioresources and Agro-Industrial Bioresidues to Health-Oriented Bioproducts: Green Recovery and Valorization of Oleanolic Acid
Oleanolic acid (OA) is a pentacyclic triterpenoid recoverable from several plant-processing residues, but its usefulness as a bioproduct feedstock depends on more than botanical occurrence. Olive leaves, olive pomace, grape pomace, and peel-rich fruit residues differ markedly in OA content, co-triterpenoid profile, moi...
