Protective Effects of Osthole against Free Radical-Induced Hemolysis of Erythrocytes

Osthole, one of the most active components of Cnidium monnieri, has different pharmacological and biological effects such as boosting the immune system, reducing rheumatoid pain, hepatoprotective, and inhibitory effect on osteoporosis. Furthermore, it showed anti-inflammatory, anti-cancer, and antioxidant properties. However, there is little information about the antioxidant effects of osthole using cell-based assays. In the current work, we used in vitro model of 2,2-azobis (2-amidinopropane) dihydrochloride (AAPH)- induced hemolysis of erythrocytes to investigate the protective effects of osthole against oxidative damage of biological membranes.

Erythrocytes were challenged with 2, 2ꞌ-azobis (2-aminopropane) dihydrochloride (AAPH) as a model oxidant in the presence and absence of osthole. The protective effects of osthole on lipid peroxidation, protein carbonyl oxidation, glutathione (GSH) content of erythrocytes were evaluated and compared with control samples.

It was found that osthole has protective effects on erythrocyte hemolysis induced by AAPH at different concentrations in a time-dependent manner. Osthole also suppressed lipid and protein oxidation as well as reductions in GSH content in a concentration and timedependent manner.

Osthole showed protective effects against free radical-induced hemolysis in rat erythrocytes. Therefore, it can be considered as a supplement for the prevention or treatment of a variety of human health problems associated with oxidative stress. However, further investigations are required to illustrate other possible impacts of osthole on cells.
