Objective: Aging is a multifactorial phenomenon, which attribute to different diseases and abnormalities in living systems. Oxidative stress, which is an important factor in aging, exacerbates this process via different mechanisms. Crocin (CR), one of the active components of saffron showed strong antioxidant effects. In the present study, anti-aging property of crocin was investigated in mice. Materials and Methods: The model of aging was induced using administration of d-galactose (500 mg/kg, s. c.) for 42 days. Animals were treated with crocin (10, 20, 40 mg/kg, i.p.) during treatment with d-galactose. At the end of treatment, levels of malondialdehyde (MDA) as a lipid peroxidation marker and glutathione content (GSH) in the liver and brain were measured. Also, biochemical factors including liver enzymes (ALT and AST), male sex hormones including testosterone and dehydroepiandrosterone-sulfate (DHEA-SO4) and pro-inflammatory markers such as tumor necrosis factor -α (TNF-α) and interlukine-6 (IL-6) in serum, were evaluated. Results: Administration of d-galactose led to induction of lipid peroxidation in liver and brain tissues, as well as elevation of AST, ALT, and pro-inflammatory cytokines and reduction of male sex hormones levels in serum. Interestingly, treatment of animals with crocin (10, 20 and 40 mg/kg) diminished lipid peroxidation in the liver and brain tissues while elevated GSH content. Also, a decline in serum levels of TNF-α and IL-6 and an elevation of male sex hormones were observed following treatment with crocin. Conclusion: Administration of crocin reduced d-galactose-induced aging in mice through inhibition of oxidative stress, reduction of inflammation and elevation of sex hormones.
