Súhrn: Recently, there has been a global interest in natural sources of phytochemicals as antioxidants and functional food ingredients. Phenolic compounds form a large group of secondary metabolites and the presence of these compounds in vegetable leaves has been related to sensory and health-promoting properties. Considering that a major part of vegetable leaves is discarded in spite of its high nutritional value, this literature review aimed to group the most recent studies, which evaluated the therapeutic and functional aspects and the technological applications of leaves. Moreover, the roles of phenolic compounds in the functional properties and in the sensory characteristics are also discussed. Studies evaluating the main technologies in the reuse of vegetable leaves are presented as well. Finally, the main challenges of the use of the leaves in the food industry are discussed. The search for new applications of by-products is an alternative to valorize these materials, in order to provide new opportunities of use for the food and pharmaceutical industries.
