Protective Effects of Mogroside V on Oxidative Stress Induced by H2O2 in Skin Fibroblasts

Purpose: Damage caused by oxidative stress leads to the premature aging of cells. Mogrosides, the main active components of Siraitia grosvenorii , have strong antioxidant activity; however, it is unclear whether mogroside V (MV) exerts these effects in skin cells. This was investigated in the present study by evaluating the protective effects of MV against oxidative damage induced by hydrogen peroxide (H 2 O 2 ) in skin fibroblasts. Methods: Mouse skin fibroblasts (MSFs) were treated with H 2 O 2 and cell viability, total antioxidant capacity, reactive oxygen species (ROS) production, malondialdehyde (MDA) content, and antioxidant enzyme activity were assessed. Results: Treatment with MV reduced the ROS level and MDA content in MSFs treated with H 2 O 2 . This was accompanied by increased superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) activities. Conclusion: MV reduces H 2 O 2 -induced oxidative stress and enhances endogenous antioxidant activity in skin fibroblasts. Thus, MV can potentially be used as an ingredient in anti-aging cosmetic products. Keywords: Siraitia grosvenorii , mogroside V, oxidative stress, antioxidant
