Erodium cicutarium is known for its total polyphenolic content, but this work reveals the first highly detailed profile of E. cicutarium, obtained with UHPLC‐LTQ OrbiTrap MS4 and UHPLC‐QqQ‐MS/MS techniques. A total of 85 phenolic compounds were identified and 17 constituents were quantified. Overall, 25 new compounds were found, which have not yet been reported for the Erodium genera, or the family Geraniaceae. Along with methanolic extracts, the so far poorly investigated water extracts exhibited in vitro antioxidant activity according to all performed assays, including the ferric reducing/antioxidant power assay (FRAP), 2,2‐diphenyl‐1‐picrylhydrazyl assay (DPPH), 2,2′‐azinobis(3‐ethylbenzthiazoline‐6‐sulfonic acid) assay (ABTS) and cupric ion reducing antioxidant capacity assay (CUPRAC). Elemental composition analysis performed with inductively coupled plasma atomic emission spectrometry (ICP‐AES) and, additionally, hydride generation atomic absorption spectrometry (HydrEA‐ETAAS) showed six most abundant elements to be decreasing as follows: Mg>Ca>K>S>P>Na, and gave first data regarding inorganic arsenic content (109.3–248.4 ng g−1). These results suggest E. cicutarium to be a valuable source of various phenolic compounds with substantial potential for further bioactivity testing.

Erodium cicutarium 的第一个广泛的多酚谱对元素组成和抗氧化活性的新见解

Erodium cicutarium 以其总多酚含量而闻名，但这项工作揭示了 E. cicutarium 的第一个高度详细的概况，这是通过 UHPLC-LTQ OrbiTrap MS4 和 UHPLC-QqQ-MS/MS 技术获得的。共鉴定出 85 种酚类化合物，并量化了 17 种成分。总体而言，发现了 25 种新化合物，这些化合物尚未在 Erodium 属或 Geraniaceae 科中报道。与甲醇提取物一起，迄今为止研究不足的水提取物根据所有进行的试验都表现出体外抗氧化活性，包括铁还原/抗氧化能力试验 (FRAP)、2,2-二苯基-1-苦基肼试验 (DPPH)、2 ,2'-肼基双（3-乙基苯并噻唑啉-6-磺酸）测定（ABTS）和铜离子还原抗氧化能力测定（CUPRAC）。用电感耦合等离子体原子发射光谱法 (ICP-AES) 和另外的氢化物发生原子吸收光谱法 (HydrEA-ETAAS) 进行的元素组成分析显示六种最丰富的元素如下减少：Mg>Ca>K>S>P >Na，并给出了有关无机砷含量 (109.3–248.4 ng g-1) 的第一个数据。这些结果表明 E. cicutarium 是各种酚类化合物的宝贵来源，具有用于进一步生物活性测试的巨大潜力。
