Comprehensive Analysis of Elemental and Metabolite Composition in Boraginaceae Species From Türkiye.

Boraginaceae plants, including four endemic species from Türkiye, were analyzed for organic and inorganic compositions using inductively coupled plasma mass spectrometry (ICP-MS) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) to explore their nutritional, medicinal, and ecological significance. This study examined 18 species, identifying key elements, such as sodium (87 600.359-118 049.272 g/kg), potassium (98 876.885-145 587.899 g/kg), and iron (70 396.436-116 416.076 g/kg), which showed significant variation. Metabolite profiling revealed the presence of alkaloids, flavonoids, and tannins in most samples. Additionally, 42 amino acids and 35 phenolic compounds were detected, with rosmarinic acid and proline being particularly abundant. Rosmarinic acid was most concentrated in Oi and Ml samples, whereas proline levels ranged from 3023.8086 to 7693.8549 nmol/mL. The study highlights the intricate metabolic and elemental profiles of Boraginaceae species, shedding light on their ecological adaptations and therapeutic potentials. Spearman correlation analysis suggested significant relationships among phenolic compounds, amino acids, and elemental compositions, indicating potential applications in nutrition, pharmacology, and biodiversity conservation.
