Phytochemical Composition, Sensory Acceptance, and Cultivation Potential of Sanguisorba verrucosa, Eruca vesicaria, and Scorzonera laciniata

Three wild edible plant species native to the Mediterranean region, Sanguisorba verrucosa, Eruca vesicaria, and Scorzonera laciniata, were investigated to evaluate their potential for cultivation and integration into human diets. All three species were positively rated in sensory evaluations and exhibited high levels of specific metabolites of nutritional and health-related interest. Moderate concentrations of β-carotene were found across all species. Notably, S. verrucosa and E. vesicaria contained appreciable amounts of vitamin C, and the phenolic content in S. verrucosa exceeded that of many commonly consumed vegetables. Each species also proved to be a rich source of distinct organic acids: S. verrucosa for fumaric acid, E. vesicaria for citric acid, and S. laciniata for quinic acid. Although domestication led to a reduction in several bioactive compounds, the nutritional value of these plants remains significant. The compositional and sensory profiles of these species highlight their promise as leafy vegetables for sustainable diets and as functional food ingredients. Furthermore, their cultivation could support biodiversity conservation efforts and reduce harvesting pressure on wild populations, contributing to more sustainable agricultural practices.
