Basic Chemical Composition, Content of Micro- And Macroelements and Antio Xidant Activity of Different Varieties of Garlic’s Leaves Polish Origin

Abstract

S t r e s z c z e n i eThe 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 ) between winter and spring varieties, as well as between winter varieties.

Chemical Composition and Concentration of Bioactive Compounds in Garlic Cultivated from Air Bulbils

“…Total polyphenol concentration and antioxidant activity were significantly higher in the Harnaś and Ornak cultivars harvested in May as compared with samples harvested in other months ( Table 2). This is in line with the lower level of polyphenolic compounds in mature leaves of Harnaś and Ornak cultivars reported by Piątkowska et al [13]. Chen et al [9] reported a much higher concentration of polyphenolic compounds and antioxidant activity measured with the DPPH method (12.64 to 22.66 mg/1 g gallic acid, 9.92 to 40.41 µmol Trolox/g) in garlic bolts and cloves from cultivars of Chinese origin (17.16 to 42.53 mg/1 g gallic acid, 4.30 to 32.02 µmol Trolox/g).…”

“…Protein and ash content decreased during plant maturation. Protein concentration in garlic grown from air bulbils, in our study, was significantly lower than in the mature garlic leaves of Harnaś and Ornak cultivars [13]. Furthermore, the same authors have reported four times higher concentration of ash in the garlic leaves of Harnaś and Ornak (14.1 and 13.1 g/100 g DM, respectively) harvested in July than in our samples of these cultivars harvested during the same month [13].…”

“…It was a higher level than that reported by Dyduch and Najda [8] in garlic leaves grown from the air bulbils harvested in May and June. Piątkowska et al [13] reported a significantly higher concentration of vitamin C in mature garlic cultivar Harnaś and Ornak leaves (45.97 and 9.88 mg/100 g FM, respectively). Vitamin C in Italian garlic cloves ranged between 11.01 and 21.59 mg/100 g FM [27].…”

“…The Agilent 1100 LC system (Agilent, Waldbronn, Germany), equipped with a degasser, binary pump, auto-sampler, and thermo-stated column compartment in a 20 • C Thermo Scientific BDS HYPERSIL C18 column (100 × 3 mm I.D., 3 µm) were employed in chromatographic separation. The choice of apportionment conditions was carried out according to Verardo et al [26] with some modifications [13]. For the MS/MS analysis the Applied Biosystems MDS Sciex (Concord, ON, Canada) API 2000 triple quadrupole mass spectrometer was used, equipped with an electrospray ionization (ESI) interface.…”

“…The July samples of both cultivars contained a level four times higher than those reported in the literature (Table 1). Piątkowska et al [13] showed that, in the mature winter leaves of Polish garlic cultivars, such as Harnaś and Ornak, harvested in July, dry matter concentration amounted to 11.89 and 13.25 g/100 FM. The level of total carbohydrates in the leaves of same cultivars was 79.6 and 89.0 g/100 g FM (66.94 and 67.17 g/100 g DM).…”
