白睡莲 (Nymphaea alba) 是睡莲科的一种水生开花植物，在传统草药中使用已有数百年历史。根据地理位置的不同，该植物具有不同的植物化学物质。在此，我们首次对多瑙河三角洲生物圈白花提取物中的多酚和黄酮类等一些抗氧化化合物进行了分离和 HPLC-MS/MS 鉴定，并研究了它们可能的抗自由基特性。超声波方法已被广泛用于从白银花的不同解剖部分（果实、花、叶、茎和根）中提取抗氧化化合物。使用超声波照射获得的提取物显示出较高的多酚（19.42 mg EqGA/100 mg 提取物）和类黄酮（0.97 mg EqQ/100 mg 提取物）含量。水果和花卉提取物显示出最高的抗氧化活性指数（AAI）。在所有白银花提取物中鉴定出的 27 种植物化学化合物中，芦丁和对香豆酸是主要成分。对白花提取物中常量元素和微量元素的含量进行了比较，发现它们的浓度取决于植物的不同解剖部位。这项研究有助于睡莲科的研究，是对罗马尼亚野生种群的白睡莲的首次详尽的植物化学研究。
Nymphaea alba is an aquatic flowering plant from the Nymphaeaceae family that has been used for hundreds of years in traditional herbal medicine. The plant is characterized by different phytochemicals, depending on the geographical location. Herein, we have carried out, for the first time, the separation and HPLC-MS/MS identification of some antioxidant compounds, such as polyphenols and flavonoids from N. alba extracts from the Danube Delta Biosphere, and investigated their possible antiradical properties. An ultrasonic method has been exhaustively used for the extraction of the antioxidant compounds from the different anatomic parts of N. alba (fruit, flower, leaf, stem, and root). The extracts that were obtained using ultrasound irradiation showed a large polyphenol (19.42 mg EqGA/100 mg extract) and flavonoid (0.97 mg EqQ/100 mg extract) content. The fruit and flower extracts showed the highest antioxidant activity index (AAI). Among the 27 phytochemical compounds identified in all of the N. alba extracts, rutin and p-coumaric acid were found as the major components. The content of macroelements and microelements in N. alba extracts were compared, and it was found that their concentrations depend on the different anatomic parts of the plant. This research contributes to the study of Nymphaeaceae family, being the first exhaustive phytochemical study of N. alba from a wild population in Romania.
