The Vaccinium genus, with over 200 species, is prized for its fruits and traditional medicinal uses. Introduced to South America in the 1980s, it has become a significant crop, particularly in Tucumán, Argentina. Southern highbush blueberries are the most cultivated. Recent research suggests that the leaves and stems of these species contain higher levels of beneficial compounds compared to fruits. This study explores the potential of V. myrtillus L. leaves and stems, typically discarded as agricultural waste, as sources of bioactive compounds. It provides the first detailed analysis of their anatomy and chemical composition, revealing high levels of phenolic compounds with antioxidant properties. Leaf extracts show stronger antioxidant activity compared to stems. Toxicity tests on Artemia salina indicate their safety for further exploration. These findings suggest that V. myrtillus L. waste by-products could be valuable as sources of bioactive compounds, promoting their application in pharmaceuticals, food, or cosmetics industries.
