Plant seeds, including those from salt tolerant (halophyte) plants, such as Chenopodium quinoa, can be considered as functional foods if they combine an adequate nutritional profile with health promoting properties [1], [2]. Having this mind and targeting the biotechnological valorization of edible halophyte plants in the context of salinisation and climate change, this work aimed to determine the nutritional, biochemical and functional properties of seeds from Suaeda vera and Arthrocaulon macrostachyum. Proximal composition, fatty acids and minerals were determined, along with the phenolic composition and antioxidant properties of ethanol and water extracts. S. vera seeds had the highest ash and fiber levels. Linoleic acid was the main fatty acid in both species, followed by oleic and palmitic acids. S. vera had the highest level of sodium, potassium, magnesium, iron and copper. The highest content of total phenolics were detected in the ethanol extract of A. macrostachyum, and aqueous ethanol (70%) extract of S. vera, and the main detected compounds were gallic, cafeic and salicylic acids. A. macrostachyum exhibited in general a higher antioxidant capacity. Our results suggest that S. vera and A. macrostachyum seeds could be further explored as sources of fatty acids, minerals and phenolic compounds with antioxidant properties. The authors declares that there is no conflict of interest.
