Investigation of Some Biochemical Parameters in Fresh and Frozen Allium ampeloprasum and Asphodelus aestivus L
In this study, analysis of the vitamins A, E, C and β-carotene, lycopene, ghrelin, oxidized and reduced glutathione (GSSG, GSH), 4-hydroxynonenal (HNE) and malondialdehyde (MDA) in fresh and frozen leek (Allium ampeloprasum) and wild leek (Asphodelus aestivus L.) were analyzed by High-Performance Liquid Chromatography (HPLC). It was found that the amounts of vitamins A, E, C and β-carotene in fresh leek were (3.10±0.15; 33.00±2.30; 52.32±2.55 and 10.10±0.90 µg/g), ghrelin, GSH, GSSG, HNE and MDA were 38.00±2.40; 110.40±8.60; 22.60±1.00; 6.50±0.20 and 0.96±0.08 µg/g, respectively. On the other hand, in wild leek the amounts of vitamin A, vitamin E, vitamin C, β-carotene and lycopene were found to be 12.60±0.90; 88.40±6.50; 645.00±32.00; 57.90±4.00 and 2.40±0.15 µg/g, respectively, ghrelin, GSH, GSSG, HNE and MDA were found to be 69.40±4.80; 313.80±28.90; 42.30±1.70; 4.51±0.24 and 0.64±0.05 µg/g. These findings suggest that, wild leek is a better food source than the leek. On the other hand, freezing of leek and wild leek, have statistically no effect on the parameters examined (p> 0.05).
