“…Deng et al (2015) observed a positive correlation between the ferulic acid content in the cuticle of Limonium bicolor (Bunge) Kuntze and the speed of sodium secretion, suggesting that ferulic acid is directly involved in the secretion of salt through saline glands [ 36 ]. These glands have not been described in species of Arthrocnemum and Sarcocornia [ 3 , 37 ]; however, the detection of ferulic acid in two of our populations of Arthrocnemum may point to its implication in certain mechanisms of tolerance to salinity.…”

(1) Background: this study describes bioactive compounds in the following halophytes: Sarcocornia (S. alpini, S. pruinosa, and S. perennis) and Arthrocnemum (A. macrostachyum). The material comes from: coastal marshes in Tinto River, Guadiana River, and some interior provinces from the Iberian Peninsula. (2) Methods: the techniques used were Folin–Ciocalteu, GC-MS, and ESI-MS/MS. (3) Results: Five phenolic acids were found in Sarcocornia: trans-cinnamic, salicylic, veratric, coumaric, and caffeic acids. In addition, in Arthronemum, ferulic acid was also detected. The obtained flavonoids were cyanidin-3-O-arabinoside, luteolin-7-glucoside, dihydroquercetin, and p-coumaroyl-glucoside. They also presented fatty acids, such as palmitic, linoleic, and oleic acids in Sarcocornia, while palmitic, linolenic, and stearic acids were the main fatty acids in A. macrostachyum. (4) Conclusions: the high diversity of the compounds identified confirms the relation between nutritional interest and salt tolerance in halophytes.

“…Plants growing in harsh conditions are usually rich in bioactive compounds. Abiotic stress, including salinity stress, triggers the synthesis of various secondary metabolites, such as phenolics, flavonoids, alkaloids, saponins, and many other compounds [ 9 , 74 ]. These compounds play a vital role in the protection of plants cells [ 74 , 75 ].…”

“…Halophytes are interesting plants as they grow and develop in harsh habitats with high salt contents, where they developed various morphological, anatomical, and physiological mechanisms to cope with salty conditions [ 7 , 8 , 9 ]. They are distributed from coastal areas on seas to deserts, which occupy about 8% of the worldwide land area [ 5 ].…”

Halophytes have been characterized as a potential resource for fiber, food, fodder, and bioactive compounds. Proximate composition, bioactive compounds, and antioxidant activity of five wild dominant halophytes (Arthrocnemummacrostachyum, Halocnemumstrobilaceum, Limoniastrummonopetalum, Limoniastrumpruinosum, and Tamarix nilotica) naturally growing along the Nile Delta coast were assessed. The soil supporting these halophytes was sandy to sand-silty, alkaline, with low organic carbon, and relatively high CaCO3. H. strobilaceum attained the highest moisture content, ash, crude fiber, lipids, and total soluble sugars. L. monopetalum showed the highest content of crude protein (18.00%), while T. nilotica had the highest content of total carbohydrates. The studied halophytes can be ranked according to their nutritive value as follows: H.strobilaceum > L.monopetalum > A.macrostachyum > L.pruinosum > T. nilotica. A. macrostachyum attained the highest amount of Na+, K+, Ca2+, and Mg2+. A. macrostachyum showed a high content of phenolic compounds, while H.strobilaceum was rich in tannins and saponin contents. The MeOH extract of A. macrostachyum and H. strobilaceum exhibited substantial antioxidant activity. The present results showed that the studied halophytes could be considered as candidates for forage production or used as green eco-friendly natural resources for bioactive compounds.

“…It is of great importance to take this fact into account within the Salicornioideae subfamily, as it is considered one of the most conflictive halophyte groups. In this subfamily of Amarathaceae, the seed characters based on color, shape, size, macro and microornamentation characteristics allow us to classify these halophytes at the level of genus, species and even in certain groups of subspecies [17,18,[52][53][54][55].…”

Background Seed germination and seedling growth constitute the first stage of a plant's life cycle for crop establishment. Arthrocnemum Moq. is a halophyte of the subfamily Salicornioideae (Amaranthaceae), which could be recognized in the foreseeable future as an emerging candidate in applied biosaline agricultural programs, mainly due to the large biomass it represents in coastal and inland saltmarshes, in addition to its interesting nutritional and pharmacological properties. However, to ensure their subsequent use as a crop, it is necessary to optimize their germination through appropriate seed priming treatments. The main goal of this work was to seek the optimization of Arthrocnemum germination process using different pretreatments: exposure to sodium chloride (100 to 1200 mM) in the dark and its subsequent transferred to distilled water separately and together with the combination of pH (5, 7, 9), salinity (0, 100, 200 mM NaCl), and iron conditions (0, 200, 400 µM FeSO4). The experiments were tested on six samples of two different species: A. meridionale (from Tunisia) and A. macrostachyum (from Spain). Results Salinity priming of seeds for 15 days in darkness improved germination percentages by almost 25% at 600 mM NaCl, in both Tunisian and Spanish species. However, keeping seeds at different salt concentrations for 30 days produced higher improvement percentages at lower concentrations in A. meridionale (100–200 mM NaCl), while in A. macrostachyum the highest improvement percentages were obtained at 600 mM NaCl (percentage improvement of 47%). When the dark time period is reduced to 5 days at higher salt concentrations, the greater germination percentages were reached in all the samples at the concentration of 800 mM NaCl, increasing the improvement of germination between 17 and 50%. Finally, the conditions of pH = 7, pretreatment in darkness at 800 mM NaCl and 400 µM or iron, turned out to be an effective medium for seed germination. Conclusions Therefore, before using Arthrocnemum seeds in applied biotechnological programs, a seed priming treatment based on prior exposure to high salt concentrations (600–1000 mM NaCl) is recommended in order to maximize germination percentages.
