Extraction of lycopene from tomato pomace and its protective effects on renal injury in diabetic rats
Abstract The aim of this study was to investigate the protective effects of lycopene from tomato pomace on renal injury in diabetic rats. Lycopene was extracted from tomato pomace. The rats were divided into control, model and 10, 20 and mg/kg lycopene groups. The diabetic nephropathy model was constructed in the latter four groups. Then, the latter three groups were treated with 10, 20 and mg/kg lycopene, respectively. After four weeks of treatment, compared with the model group, in 20 and 40 mg/kg lycopene groups the serum fasting plasma glucose level was decreased (P < 0.05), the fasting insulin level was increased (P < 0.05), the renal index and 24-h urinary protein level were decreased (P < 0.05), the blood urea nitrogen and serum creatinine levels were decreased (P < 0.05), the renal tissue superoxide dismutase and glutathione peroxidase levels were increased (P < 0.05), the renal tissue malondialdehyde level was decreased (P < 0.05), and the serum tumor necrosis factor α, interleukin 6 and hypersensitive C-reactive protein levels were decreased (P < 0.05). In conclusion, lycopene from tomato pomace can alleviate renal injury in diabetic rats. The mechanism may be related to the resistance of oxidative stress and inflammatory response.
