(Vaill.) L. (field marigold, Asteraceae) is an alimurgic plant, whose flowers and leaves are a common part of local food dishes. The diversity in polar specialized metabolites is herein unraveled, with the aim to further promote and valorize the food use of the plant. To this purpose, following the plant dissection of its organs (florets, fruits, leaves, bracts, stems, and roots), ultrasound assisted maceration has been employed in order to recover phenols and polyphenols. Through an untargeted UHPLC-HR MS (Ultra-High-Performance Liquid Chromatography-High-Resolution Mass Spectrometry) approach, and deeper investigation of the fragmentation patterns of each compound by tandem mass spectrometry, the florets' constitution in triterpene saponins and flavonol glycosides has been highlighted, whereas hydroxycinnamoyl compounds are mainly in bracts and fruits. The antiradical and reducing capabilities of the organs' extracts have been assessed, and data acquired have been analyzed by cluster analysis, which allowed bracts and fruits to be observed, despite their negligible food use, as the most active extracts. Chemical and antioxidant data on the diverse organs of field marigold suggest new investigative food and nutraceutical scenarios of this plant, also revalorizing and preserving its traditional uses.
（Vaill.）L.（田野金盏花，菊科）是一种食用植物，其花和叶是当地菜肴的常见组成部分。本文揭示了极地特化代谢产物的多样性，旨在进一步推广和提升该植物在食品中的应用价值。为此，在对其器官（小花、果实、叶、苞片、茎和根）进行解剖后，采用超声辅助浸渍法来提取酚类和多酚类物质。通过非靶向超高效液相色谱-高分辨率质谱（UHPLC-HR MS）方法，并利用串联质谱对每种化合物的碎片模式进行深入研究，突出了小花中三萜皂苷和黄酮醇苷的组成，而羟基肉桂酰化合物主要存在于苞片和果实中。评估了各器官提取物的抗自由基和还原能力，并通过聚类分析对所获得的数据进行了分析，结果发现，尽管苞片和果实的食用价值可忽略不计，但它们却是活性最强的提取物。田野金盏花不同器官的化学和抗氧化数据为该植物在食品和营养保健方面的新研究提供了思路，同时也提升并保留了其传统用途。
