violacea_ was the species with the highest fiber in the flowers, which oscillated between 15.772% and 16.927%; in the case of _A. ampleprorasum_, its fiber ranged between 9.269% and 10.876%. On average, garden garlic flowers contained 38.05% more fiber. The carbohydrate level was not significantly different (\(p\) = 0.4518). The amount of carbohydrates was slightly lower in wild garlic flowers which oscillated between 63.591% and 66.117%. Flowers of both species studied are characterized by a low energy content. Energy values ranged from 347.003 to 349.054 kcal\(\cdot\)100 g\({}^{-1}\) dry weight for garden garlic flowers and from 374.004 to 380.256 kcal\(\cdot\)100 g\({}^{-1}\) dry weight for wild leek flowers, with higher significant levels (\(p\) = 0.0001) for _A. ampleprorasum_ flowers. Coefficients of variability (CV) showed a wide range of values in the nutritional parameters. In general, garden garlic flowers had lower coefficients of variability than those shown by the parameters of wild leek flowers. In particular, _A. ampleprorasum_ flowers had the highest variability for nutritional parameters such as ash (14.18%), fat (11.32%) and fiber (approximately 8%). The remaining parameters for these flowers were less variable, with coefficients of variability oscillating between 0.09% for moisture and 3.65% for protein. The nutritional parameters that showed the highest variability value in garden garlic flowers were fat (12.16%) and crude protein (4.37%). _A. ampleprorasum_ was the species with a higher content of total polyphenols in the flowers, which oscillated between 1610.24 mg EAG-100 g\({}^{-1}\) dw and 2058.09 mg EAG-100 g\({}^{-1}\) dw; in the case of _T. violacea_, its total polyphenols ranged between 1252.21 mg EAG-100 g\({}^{-1}\) dw and 1268.15 mg EAG-100 g\({}^{-1}\) dw. On average, wild leek flowers contain 32% more total polyphenols. The antiradical activity measured via DPPH assay content in the flowers tested ranged from 2407.22 umol TE\(\cdot\)100 g\({}^{-1}\) (_A. ampleprorasum_) to 4333.86 umol TE\(\cdot\)100 g\({}^{-1}\) (_T. violacea_), with the differences found being statistically significant (\(p\) = 0.0002). Variability of the total polyphenic content is higher for wild leek flowers (12.20%), while the antiradical activity via a DPPH assay also shows a greater coefficient of variability for the flowers of wild leek (approximately equal to 8.06%). Sixteen mineral elements were analyzed and classified in order of highest to lowest concentrations in macroelements (Ca, K, Mg, P and Na), microelements (Fe, Mn, Zn, Cu, B, Cr, Se and Mo) and the elements characterized as heavy metals (Cd, Hg and Pb). In garden garlic flowers, the most abundant macromineral was calcium, which ranged in these flowers between 492.43 mg 100 g\({}^{-1}\) dw and 640.25 mg 100 g\({}^{-1}\) dw. In wild leek flowers, the most abundant macromineral was potassium, which ranged in these flowers between 347.68 mg 100 g\({}^{-1}\) dw and 393.15 mg 100 g\({}^{-1}\) dw. Phosphorus and potassium concentrations in garden garlic flowers were very similar (approximately 330 mg 100 g\({}^{-1}\) dw), and for wild leek flowers, the concentrations of phosphorus and calcium were similar (305 mg 100 g\({}^{-1}\) dw). On average, the concentration of magnesium in the flowers was 0.5% minor for wild leek, while sodium was present in higher concentrations (52.5%) in garden garlic flowers. Except for K and Mg, all the differences found in the concentrations of the macrominerals in the flowers were statistically significant. Regarding microminerals, the high concentration of iron in garden garlic flowers stood out, with 32.786 mg 100 g\({}^{-1}\) dw compared to 3.396 mg 100 g\({}^{-1}\) dw found in wild leek flowers. Zinc was the second most abundant micromineral in both types of flowers, with an average higher concentration (32.57%) in wild leek flowers. Boron was the third most abundant micromineral in both types of flowers, with similar concentrations between both flowers.
