Antioxidant polyphenols from fruits of the Myrtle family

桃金娘科(桃金娘科)的许多物种在热带和亚热带世界都是受欢迎的食用植物。此外，一些还被用于从南美到东南亚的不同传统实践中的药用。在1，1-二苯基-2-苦基肼(DPPH)实验中，两种杨梅属植物的果实显示出很强的抗氧化活性，随后对丁香亚族相关植物的民族医学和化学分类的研究导致了这样的假设，即这些水果含有类黄酮或其他多酚类化合物，对人类的生物分子具有氧化保护作用。我们将使用DPPH法分析来自该分类群的10种常见可食用树种的果实的抗氧化活性。将对最有效的提取物进行更详细的研究，以分离和鉴定特定的多酚抗氧化剂植物化学物质。预计新的抗氧化剂化合物将被发现，其化学结构将被充分阐明。然后，这项研究将使用开发的分析工具，密切关注由最活跃的水果制成的饮料和醋，以确定水果中的有益植物化学物质是否可以在商业产品中检测到。

Many species of the Myrtle family (Myrtaceae) are popular edibles throughout the tropical and subtropical world. In addition, some are used medicinally in divergent traditional practices from South America to Southeast Asia. The fruits of two species of Eugenia (Myrtaceae) have shown a strong antioxidant activity in the 1,1-diphenyl-2- picrylhydrazyl (DPPH) assay, and subsequent ethnomedical and chemotaxonomic study of related plants in the subtribe Eugeniinae have led to the hypothesis that these fruits contain flavonoids or other polyphenolic compounds that exhibit an oxidative protection to biomolecules in humans. The fruits of ten popular edible species from this taxa will be analyzed for antioxidant activity using the DPPH assay. The most active extracts will be studied in greater detail to isolate and identify specific polyphenolic antioxidant phytochemicals. It is expected that novel antioxidant compounds will be discovered, and their chemical structures will be fully elucidated. This research will then use the analytical tools developed to look closely at beverages and vinegar made from the most active fruit to ascertain whether the beneficial phytochemicals in the fruit can be detected in commercial products.
