The flavonoid content of Zostera noltei leaves was investigated over a broad spatial scale using chromatographic and spectroscopic techniques (HPLC-DAD, LC/MS and NMR). Samples were collected at fifteen localities covering Mediterranean Sea and NE Atlantic coast, and representative of three types of coastal ecosystems: mesotidal bays, coastal lagoons, and open-sea. Three geographically distinct flavonoid chemotypes were identified on the basis of their respective major compound. One is characterized by apigenin 7-sulfate (Eastern part of Gulf of Cadiz), one by diosmetin 7-sulfate (French Atlantic coast and Mediterranean Sea), and the third contained similar quantities of the above two compounds (Mauritania and South Portugal). Our results show that metabolomic profiling using a combination of analytical techniques is a tool of choice to characterize chemical phenotype accurately. This work emphasizes for the first time the spatial variability in the flavonoid chemistry of Z. noltei throughout Atlantic and Mediterranean range, and constitutes the first report of chemical races in the Zosteraceae family. This infraspecific chemical differentiation should be considered when dealing with the role of Z. noltei in coastal ecosystems or in the selection of the best population donor for Z. noltei beds restoration. Combined with molecular identification, phenolic fingerprinting might be helpful to elucidate the evolutionary history of Z. noltei.

海草 Zostera noltei Hornem 的酚类化学。第 1 部分:三个不同地理区域中三种种下类黄酮化学型的第一个证据

使用色谱和光谱技术(HPLC-DAD、LC/MS 和 NMR)在广泛的空间尺度上研究了带叶草叶的类黄酮含量。在覆盖地中海和东北大西洋沿岸的 15 个地点收集了样本,这些样本代表了三种沿海生态系统:中潮汐海湾、沿海泻湖和公海。根据它们各自的主要化合物鉴定了三种地理上不同的类黄酮化学型。一种是芹菜素 7-硫酸盐(加的斯湾东部),一种是 7-硫酸地奥司美汀(法国大西洋沿岸和地中海),第三种是上述两种化合物(毛里塔尼亚和葡萄牙南部)的含量相似。我们的结果表明,使用组合分析技术进行代谢组学分析是准确表征化学表型的首选工具。这项工作首次强调了在整个大西洋和地中海地区的 Z. noltei 类黄酮化学的空间变异性,并构成了 Zosteraceae 科化学小种的第一份报告。在处理 Z. noltei 在沿海生态系统中的作用或选择用于 Z. noltei 床恢复的最佳种群供体时,应考虑这种种下化学分化。结合分子鉴定,酚类指纹图谱可能有助于阐明 Z. noltei 的进化历史。noltei 在整个大西洋和地中海范围内,构成了带状疱疹科化学小种的第一份报告。在处理 Z. noltei 在沿海生态系统中的作用或选择用于 Z. noltei 床恢复的最佳种群供体时,应考虑这种种下化学分化。结合分子鉴定,酚类指纹图谱可能有助于阐明 Z. noltei 的进化历史。noltei 在整个大西洋和地中海范围内,构成了带状疱疹科化学小种的第一份报告。在处理 Z. noltei 在沿海生态系统中的作用或选择用于 Z. noltei 床恢复的最佳种群供体时,应考虑这种种下化学分化。结合分子鉴定,酚类指纹图谱可能有助于阐明 Z. noltei 的进化历史。
