Tunisian Species: Important Sources of Polyphenols, Organic Acids, Minerals, and Proteins across Various Plant Organs.

and are wild edible Mediterranean plants used in the human diet. This study presents the initial findings on the phytochemical characterization of Tunisian and organs. It examined their mineral, sugar, organic acid, polyphenolic, and seed storage protein contents, as well as their antioxidant potential. In , stems had high sodium and potassium contents, while the immature and mature seeds were rich in calcium and magnesium. However, had high potassium levels in stems and high sodium and calcium levels in the flowers. showed substantial fructose variation among its organs. Conversely, exhibited significant heterogeneity in glucose, sucrose, and maltose levels across its organs, with maltose exclusively detected in the immature seeds. A notable organ-dependent distribution of organic acids was observed among the two species. Higher levels of phenolic contents were detected in both mature and immature seeds in both species compared to the other plant parts. The seeds possessed higher antioxidant activities than other plant organs. In both and seeds, albumins and globulins were the predominant protein fractions. This study brings evidence supporting the important potential of organs as sources of nutrients with antioxidant properties for producing functional food.
