The present study aimed to investigate the effect and possible mechanism of action of crocetin on the high cholesterol diet (HCD) induced atherosclerosis rat. The Wistar rats were used in the current investigation. The rats were divided into following group, Group I: control, Group II: HCD induced AS, Group III: AS + crocetin (25 mg/kg), Group IV: AS + crocetin (50 mg/kg) and Group V: AS + Simvastatin, respectively. AS was induced in the rats using the vitamin Dand HCD. The rats received the pre-determined treatment for the 10 weeks. After the study period, the level of lipid profile, malonaldehyde (MDA) and superoxide dismutase (SOD) were also estimated. The proinflammatory cytokines viz., tumor necrosis factor (TNF)-α and interleukin (IL)-6 were scrutinized using the ELISA kits. We also estimated the expression of phosphorylated p38 (p-p38) MAPK using the Western blot techniques. The results revealed that the AS was successfully induced in the rats. The AS control group rats showed the modulated level of lipid profile, and decreased the level of the SOD and boost the level of the MDA as compared with the normalcontrol. However, crocetin thrived in enhancing the lipid profile toward the standard value in the normal control group rats. The crocetin and simvastatin group rats significantly inhibited the expression of the p-p38 MAPK as compared to the AS group rats. In conclusion, the current investigation revealed that the crocetin reduced the HCD induced dyslipidemia in the Wistar rats, the possible mechanism of action may be connected to the antioxidative, down regulating of p-p38 MAPK and antiinflammatory effect by crocetin.
