Spartina maritima and Puccinellia maritima are two fascinating but underexplored halophytic species, and herein, the chemical profile of their hexane extracts is described. Terpenoids and sterols were the most abundant chemical groups in both species. The second dominant class was alcohols and the third esters of fatty acids. The chemical lipophilic profile of both S. maritima and P. maritima is herein reported for the first time. Through the accomplished data, it is possible to conclude that these species are rich in essential compounds that can be relevant to endorse their use as nutraceuticals. Furthermore, through a principal component analysis, a clear differentiation between the taxa was achieved, which indicates that their response to salinity stress is different. That fact was confirmed by the pathway enrichment analysis, which showed that the induced changes in metabolic pathways vary in each species.
互花米草和大米草是两种引人入胜但尚未充分研究的盐生植物，本文描述了它们正己烷提取物的化学特征。萜类化合物和甾醇是这两个物种中最丰富的化学物质。第二大类是醇类，第三大类是脂肪酸酯。本文首次报道了这两种互花米草和大米草的化学亲脂性特征。通过完成的数据，可以得出结论，这些物种富含的必需化合物可能与其作为营养保健品的用途有关。此外，通过主成分分析，实现了对分类群的清晰区分，这表明它们对盐胁迫的反应不同。这一事实通过途径富集分析得到了证实，该分析表明，每个物种的代谢途径的诱导变化各不相同。
