The objective of the present study was to analyse the fruit yield and the lipid and phenolic composition of the seeds from the edible halophyte Crithmum maritimum growing in different types of soil with variable physicochemical properties. Seed oil content ranged between 8.39–11.66 % and showed high nutritional value, and the phenolic composition (423−603 mg TPC 100 g−1) presented high levels of quercetin-type compounds with high pharmaceutical interest. The strong conservation of these traits, together with a high and stable fruit production, suggests that C. maritimum could be cultivated in soils with no agronomical relevance to produce seeds as an accessible and environmentally friendly source of good quality oil and phenolics for industrial purposes. © 2022 Elsevier Inc.
