Antioxidant Capacity of Free Volatile Compounds from <i>Olea europaea</i> L. cv. Oblica Leaves Depending on the Vegetation Stage

Previous research on specialized metabolites of olive leaves has focused on the phenolic components and their biological role. The research in this article focuses on the metabolites that form free volatile compounds (FVCs). The composition of FVCs is divided into compounds isolated in the oil phase...
