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.
越橘属有200多个物种，因其果实和传统药用价值而备受珍视。20世纪80年代被引入南美洲，它已成为一种重要作物，尤其是在阿根廷的图库曼。南方高丛蓝莓种植最为广泛。最近的研究表明，与果实相比，这些物种的叶子和茎含有更高水平的有益化合物。本研究探讨了通常作为农业废弃物丢弃的欧洲越橘的叶子和茎作为生物活性化合物来源的潜力。它首次对其解剖结构和化学成分进行了详细分析，揭示了具有抗氧化特性的高水平酚类化合物。叶提取物的抗氧化活性比茎更强。对卤虫的毒性测试表明它们对于进一步探索是安全的。这些发现表明，欧洲越橘的废弃副产品作为生物活性化合物的来源可能很有价值，促进它们在制药、食品或化妆品行业的应用。
