is a halophyte belonging to the botanical subfamily Salicornioideae that forms extensive perennial salt marsh patches. This subfamily has excellent potential, still unexplored, as a source of food, medicine, and phytoremediation. This study aimed to evaluate the lipophilic composition of the different organs inhabiting salt marshes of Ria de Aveiro under different stress regimes. For this purpose, the lipophilic content was extracted with hexane and subsequent GC-MS analysis of the extracts for each plant organ, which was collected in three different salt marshes of the Ria de Aveiro. High sugar content was detected in the stems, whereas in fruiting articles, the higher content was in fatty acids. Shorter-chain organic acids were concentrated in the stems and vegetative articles; waxes were detected in greater quantity in photosynthetic organs. More or less stressful environments induce changes in the ratio and composition of molecules, such as acclimatization and oxidative stress reduction strategies; for example, fatty acid content was higher in plants subjected to a higher stress regime. These data contribute to understand the metabolic pathways of the species under study, suggesting new research approaches to its potential as food, medicine, and phytoremediator.
是一种属于盐角草亚科的盐生植物，形成广泛的多年生盐沼斑块。作为食物、药物和植物修复的来源，该亚科具有尚未开发的巨大潜力。本研究旨在评估在不同胁迫条件下，栖息于阿威罗河口盐沼的不同器官的亲脂性成分。为此，用己烷提取亲脂性成分，随后对从阿威罗河口三个不同盐沼采集的每个植物器官的提取物进行气相色谱 - 质谱分析。茎中检测到高糖含量，而在结果实的部分，脂肪酸含量较高。短链有机酸集中在茎和营养部分；光合器官中检测到的蜡含量更高。或多或少的胁迫环境会诱导分子比例和组成的变化，如驯化和氧化应激降低策略；例如，在较高胁迫条件下的植物中脂肪酸含量更高。这些数据有助于理解所研究物种的代谢途径，为其作为食物、药物和植物修复剂的潜力提出新的研究方法。
