Obtaining and assessing the biological activity of quercetin included in polydisperse nanoparticles of zein
Keywords:
HaCaT keratinocytes, zein, quercetin, nanostructures, oxidative stress, DNA damageAbstract
The corn protein zein was used to obtain quercetin-containing nanoparticles. It has been shown that quercetin included in the zein matrix retains antiradical activity in the reaction with 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) radical cations. It was found that both native quercetin and structured quercetin in zein nanoparticles reduce damage to plasma membranes and nuclear DNA of cells caused by bactericidal UV irradiation. Thus, corn protein zein can be used to obtain quercetin-containing nanoparticles that retain the biological activity of native quercetin.
