Petroselinum sativum protects HepG2 cells from cytotoxicity and oxidative stress induced by hydrogen peroxide.

A number of liver diseases are known to be caused by oxidative stress. Petroselinum sativum (P. sativum; parsley) is popular for its anti-inflammatory, antimicrobial, anticancer, antioxidant and antidiabetic activities. However, till date the hepatoprotective potential of chloroform extract of P. sativum (PSA) on hydrogen peroxide (H2O2) induced cytotoxicity and oxidative stress in human liver (HepG2) cells have not been studied. Therefore, this study was framed to evaluate whether the levels of hydrogen peroxide (H2O2) induced cytotoxicity and oxidative stress in HepG2 cells could be diminished by pretreating the cells with PSA. MTT assay, NRU assay, morphological alterations, glutathione (GSH) depletion, lipid peroxidation (LPO), ROS generation and loss of mitochondrial membrane potential (MMP) were assessed by using non-cytotoxic concentrations (5, 10 and 25 μg/mL) of PSA against H2O2 (0.25 mM) induced damage in HepG2 cells. The results demonstrated that pretreatment of HepG2 cells with PSA offered protective properties by lowering the LPO and ROS generation and elevating the cell viability, GSH and MMP levels. Together, these results suggest that PSA has the hepatoprotective effect on H2O2 induced cell death in HepG2 cells.
