This study aimed to comparatively determine the biochemical characteristics, Dualex indices, and macro-micro
nutrient element contents of three Allium species naturally distributed in Türkiye and cultivated under ex situ conditions. The
plant material consisted of Allium schoenoprasum L., Allium scorodoprasum subsp. rotundum (L.) Stearn, and Allium vineale
L., grown in the Medicinal and Aromatic Plants Garden of Van Yüzüncü Yıl University (Van, Türkiye). During the vegetation
period, leaf samples were collected and analyzed for total phenolic content, total flavonoid content, total antioxidant activity,
total ash, total dry matter, Dualex indices [nitrogen balance index (NBI), chlorophyll, flavonoid, and anthocyanin], and macromicro
nutrient elements using standard biochemical and instrumental methods. The results indicated that total ash ranged
between 7.04-13.93% and total dry matter between 31.22-33.25%. Total flavonoid content varied from 16.66 to 17.60 mg QE
100 g⁻¹, total phenolic content from 169.44 to 181.52 mg GAE g⁻¹, and total antioxidant activity from 75.90 to 91.68 μmol
TE g⁻¹. Dualex measurements showed NBI values between 24.20-125.40 dx, chlorophyll 25.67-33.90 dx, flavonoid 0.27-1.69
dx, and anthocyanin 0.05-0.09 dx. When evaluated within each Allium species, it was determined that the concentrations of
potassium, calcium, magnesium, zinc, and copper metals were higher in Allium scorodoprasum subsp. rotundum compared to
the concentrations of other species. In biochemical content analyses, it was found that Allium vineale L. species had higher
values. Overall, the findings demonstrate significant interspecific variation in nutritional and phytochemical traits, suggesting
that A. vineale may be prioritized for phytochemical utilization and A. scorodoprasum subsp. rotundum for mineral nutrition
studies and breeding programs.
