Abstract
This study was conducted to determine the effect of a natural polyphenolic isoflavone antioxidant (Glabridin) on low-density lipoprotein (LDL) oxidation. Determination of the extent of LDL oxidation was done by measuring the formation of Thiobarbituric acid reactive substances (TBARS). After oral administration of licorice-root ethanol extract to healthy subjects for 6 months, the subjects’ oxidative stress level as well as plasma LDL oxidation reduced by 20%. We concluded that dietary consumption of glabridin protects LDL from oxidation.
