Abstract

We evaluated the antioxidant properties of mulberry leaves extract (MLE) and flavonoids isolated from MLE. MLE was prepared by extraction with methanol. Flavonoids were analyzed by high-performance liquid chromatography. Oxidative hemolysis of normal human red blood cells (RBCs) was induced by the aqueous peroxyl radical [2,2′-Azobis (2-amidinopropane) dihydrochloride, AAPH]. MLE contained three flavonoids in the order quercetin (QC) > kaempferol (KF) > astragalin (AG). Oxidative hemolysis of RBCs induced by AAPH was suppressed by MLE, AG, KF, and QC in a time- and dose-dependent manner. MLE and these three flavonoids prevented the depletion of cystosolic antioxidant glutathione (GSH) in RBCs. AG had the greatest protective effect against AAPH-induced oxidative hemolysis and GSH depletion in RBCs.
