Description 361-364
Of Brassicaceous plants, kale (Brassica oleraceae L. var. acephala DC)
contains polyphenols, flavonoids, isoflavones and glucosinolates and so has
antioxidant and anticarcinogenic properties. Antioxidants inhibit negative
effects of free radicals and may, therefore, protect tissues against oxidative
damage. Oxidation of lipoproteins is a key event in the development of
atherosclerosis. In the current study, the levels of total phenolic and
flavonoid contents and total antioxidant capacity of methanolic and aqueous
extracts of kale leaves were determined. In addition, the susceptibility of
isolated lipoproteins — very low density lipoprotein (VLDL) and low density
lipoprotein (LDL) to the
Cu2+-induced oxidation with various concentrations of metanolic and
aqueous extracts was evaluated as t-lag values. Although aqueous extract had higher
total antioxidant capacity, methanolic extract had higher total phenolic and
flavonoid content (P
