“…The free sugars in the aerial parts of S. marianum have been widely discussed. Tian et al and Zhauynbaeva et al reported the presence of glucose, galactose, mannose, rhamnose, xylose, and arabinose [32,33]. Additionally, mannitol, sucrose, fructose, raffinose, arabinose, and galactose were detected in the stems of the plant [31].…”

Silybum marianum and Silybum eburneum are wild edible Mediterranean plants used in the human diet. This study presents the initial findings on the phytochemical characterization of Tunisian S. marianum and S. eburneum organs. It examined their mineral, sugar, organic acid, polyphenolic, and seed storage protein contents, as well as their antioxidant potential. In S. marianum, stems had high sodium and potassium contents, while the immature and mature seeds were rich in calcium and magnesium. However, S. eburneum had high potassium levels in stems and high sodium and calcium levels in the flowers. S. marianum showed substantial fructose variation among its organs. Conversely, S. eburneum 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 S. marianum and S. eburneum seeds, albumins and globulins were the predominant protein fractions. This study brings evidence supporting the important potential of Silybum organs as sources of nutrients with antioxidant properties for producing functional food.

The genus Silybum comprises two closely related species, S. marianum and S. eburneum, both of which are listed among the most highly valued wild edible plants. Various local rural communities in the Mediterranean basin have incorporated these plants into their diets. In this study, we investigated the organs (stems, leaves, flowers, immature seeds, and mature seeds) of wild, potassium, edible S. marianum and S. eburneum collected from two Tunisian regions for their mineral composition, polyphenolic contents, organic acids, seed storage proteins, as well as their antioxidant potential. The Flame atomic spectroscopy revealed that, in S. marianum, stems had high sodium, while potassium and calcium were in the flower and leaf. S. eburneum had high sodium in stems and potassium and calcium in the flower, with variations in magnesium and other minerals. S. marianum shows substantial fructose variation among its organs, with the highest content in the stem (3.54 mg/g DW) and the lowest in immature seeds (0.01 mg/g DW). Conversely, S. eburneum exhibits significant heterogeneity in glucose, sucrose, and maltose levels across its organs, with maltose exclusively detected in immature seeds. A notable organ-dependent distribution of organic acids was observed for oxalic, quinic, citric, malic, succinic, lactic, formic, acetic, and propionic acids among the two species. The phenolic contents were calorimetrically evaluated and further submitted to an LC-MS analysis. Higher levels were detected in both mature and immature seeds in both species compared to the other plant parts. Also, the seeds possessed higher antioxidant activities. A total of 32 phenolics were identified with 3,4-di-O-caffeoyquinic acid, 4,5-di-O-caffeoyquinic acid, syringic acid, protocatechuic acid, naringenin, apigenin, and quercetin were detected as the dominant compounds. In both S. marianum and S. eburneum, albumins and globulins are the predominant protein fractions in both mature and immature seeds and the storage protein fraction was mostly affected by the maturity stage. This current study substantiates the versatile utility of Silybum as a sustainable resource with significant potential for its nutritional applications in the production of functional foods across diverse sectors of the food industry.
