Abstract
Introduction: This study aimed to investigate the effect of saffron extract and crocin on blood biomarkers associated with obesity using the rat model. Methods: Obesity was induced by feeding a high-fat diet to 42 male Sprague-Dawley rats for 12 weeks after which they were equally distributed into seven groups. Three groups served as controls namely normal diet (ND) high-fat diet (HFD) and high-fat diet plus orlistat (HFD ORL) while the remaining four treatment groups consisted of HFD added low or high dose (40 and 80 mg/kg/day) of either saffron extract or crocin in the food. At the end of 8 weeks blood samples were collected by cardiac puncture for biochemical analysis. Results: Obese rats treated with a high dose of saffron extract and crocin showed significantly lower plasma glucose levels (5.26 and 5.67 mmol/L respectively) than the HFD rats (6.92 mmol/L). Saffron extract and crocin at a high dose showed significantly lower levels of plasma insulin (3.97 and 3.88 ng/mL respctively) compared to HFD control (5.41 ng/mL). Adiponectin levels significantly increased in obese rats fed saffron extract and crocin at high doses (7.44 and 7.92 g/mL respectively) compared to HFD control (5.34 g/mL). Ghrelin level significantly increased from 419.10 to 284.10 pg/mL while leptin level significantly decreased from 8.08 to 5.68 ng/mL for the high dose crocin groups compared to HFD control. No significant differences in plasma serotonin levels were found among the groups. Conclusion : Saffron extract and crocin show potential in reducing blood biomarkers associated with obesity as well as anti-inflammatory and regulatory potential of adipocytokines in an animal model.
