Jabuticaba (Myrciaria jaboticaba (Vell.) Berg) is a Brazilian berry, very appreciated for in natura consumption. However, its epicarp is not normally consumed due to its stiffness and astringent taste, and in manufacture of products from jabuticaba fruit, it is responsible for the generation of large amounts of residues. The exploration of by-products is becoming important for the obtainment of valuable bioactive compounds for food and pharmaceutical industries. In this context, jabuticaba epicarp was studied regarding its chemical composition, namely in terms of phenolic compounds, tocopherols, and organic acids, and its bioactive properties, such as antioxidant, anti-proliferate, anti-inflammatory, and antimicrobial activities. A total of sixteen phenolic compounds, four tocopherols and six organic acids were identified in jabuticaba epicarp. Regarding bioactive properties, it showed high antioxidant activity, also presenting moderate anti-inflammatory, anti-proliferative, and antimicrobial activities. The extract did not present hepatotoxicity, confirming the possibility of its applications without toxicity issues.
嘉宝果（Myrciaria jaboticaba (Vell.) Berg）是一种巴西浆果，因其可生食而备受推崇。然而，由于其表皮坚硬且具有收敛性，通常不会被食用，而且在加工嘉宝果制品时，它会产生大量的残渣。探索副产物对于从食品和制药行业获得有价值的生物活性化合物变得越来越重要。在这种情况下，研究了嘉宝果的果皮，以确定其化学成分，特别是酚类化合物、生育酚和有机酸，以及它的生物活性特性，如抗氧化、抗增殖、抗炎和抗菌活性。在嘉宝果的果皮中共鉴定出十六种酚类化合物、四种生育酚和六种有机酸。关于生物活性特性，它表现出高抗氧化活性，同时还具有中等的抗炎、抗增殖和抗菌活性。提取物没有表现出肝毒性，这证实了其在没有毒性问题的情况下应用的可能性。
