The aim of this study was to comparison of chemical components and antioxidant activity in leaves of winter and spring varieties of garlic, obtained from POLAN Company; Krakow, Poland) as well as in leaves of wild (bear’s) garlic. The content of basic chemical components were determined according to the AOAC methods. Selected minerals content was determined according to the PN procedure. Vitamin C and polyphenols were determined using the Tillman’s and Folin-Ciocalteau’s methods, respectively. The ability to scavenging of the ABTS•+ was analyzed by Re et al. method. Leaves of wild garlic had the significantly lowest amount of dry matter (79.0 g·kg⁻¹), proteins (13.7 g·kg⁻¹), total carbohydrates (50.8 g·kg⁻¹), dietary fiber (26.9 g·kg⁻¹), ash (8.9 g·kg⁻¹), vitamin C (956.1 mg·kg⁻¹), and antioxidant activity (25.0 mmol TEAC·kg⁻¹), but the highest level of crude fat (5.6 g·kg⁻¹), potassium (34.6 g·kg⁻¹), magnesium (1.72 g·kg⁻¹), iron (230.3 mg·kg⁻¹) and zinc (58.8 mg·kg⁻¹) as compared to winter and spring varieties. At the same time, there was no unambiguous differences in the level of basic chemical components (proteins 20.9 ÷ 35.7 g·kg⁻¹, fat 1.6 ÷ 2.8 g·kg⁻¹, total carbohydrates 61.3 ÷ 116.5 g·kg⁻¹, fibre 33.7 ÷ 57.0 g·kg⁻¹, ash 8.9 ÷ 14.1 g·kg⁻¹), antioxidants (vitamin C 75.4 ÷ 459.7 mg·kg⁻¹, polyphenols 335.3 ÷ 1895.1 mg·kg⁻¹), antioxidant activity (27.0 ÷ 30.1 mmol TEAC·kg⁻¹) and the amount of minerals (calcium 7.55 ÷ 28.9 g·kg⁻¹, potassium 15.9 ÷ 28.0 g·kg⁻¹, magnesium 0.85 ÷ 1.32 g·kg⁻¹, sulphur 2.41 ÷ 6.22 g·kg⁻¹, iron 34.4 ÷ 85.7 mg·kg⁻¹, zinc 9.32 ÷ 13.8 mg·kg⁻¹) between winter and spring varieties, as well as between winter varieties.
