Spices and condiments, small but an integral part of the daily diet, are known to affect physiological functions. This study evaluated the effects of mahanimbine, a major carbazole alkaloid from Murraya koenigii (curry leaves), against progression of high-fat diet (HFD)-induced metabolic complications in mice (male and female). Mahanimbine at 2 mg/kg (HFD + LD) and 4 mg/kg (HFD + HD) of body weight was administered daily along with HFD feeding for 12 weeks. At the end of the study, male HFD + LD and HFD + HD groups showed 51.70 ± 3.59% and 47.37 ± 3.73% weight gain, respectively, as compared with 71.02 ± 6.04% in HFD fed mice whereas female HFD + LD and HFD + HD groups showed 24.31 ± 1.68% and 25.10 ± 2.61% weight gain as compared with HFD group with 36.69 ± 3.60% of weight gain. Mahanimbine prevented HFD-induced hyperlipidemia and fat accumulation in adipose tissue and liver along with therestricted progression of systemic inflammation and oxidative stress. Moreover, mahanimbine treatment improved glucose clearance and upregulated the expression of insulin responsive genes in liver and adipose tissue. Male and female mice showed different traits in development of HFD-induced metabolic disturbances; however, mahanimbine treatment exerted similar effects in both the sexes. In addition, mahanimbine lowered the absorption of dietary fat resulting in dietary fat excretion. In conclusion, daily consumption of mahanimbine and thereby curry leaves may alleviate development of HFD-induced metabolic alterations. © 2016 BioFactors, 43(2):220-231, 2017.
