Abstract

The study was performed to investigate the effects of enzyme treated garlic (EG) and its natural resources composites on lipid levels in serum and liver of rats fed a high fat diet. Four different types of EG-composite extracts prepared: EG and EG + grape peel (EGG), EG + Persimmon (EGP) and EG + Catechu (EGC) by mixed 9.5:0.5, 9:1 and 8:2 (w/w) ratios, respectively. DPPH and ABTS radical scavenging activity in vitro, show the highest in EG + Catechu (EGC) composite by mixed 8:2 (w/w). EG and EG-composites extracts (8:2, w/w) were administered orally to SD-male rats at a concentration of 2.5 g/kg/day for 5 weeks. Total lipid and cholesterol contents in serum were significantly lower in EGC group than control group, and triglyceride content was the lowest in EGP group by 54.29 mg/dL. HDL-cholesterol contents were significantly higher in EGP and EGC groups. LDL-cholesterol content was lower in EG group than EG-composite groups, and VLDL cholesterol content was the lowest in EGP group. GOT, GPT and ALP activity was significantly lower in EGP group. Total lipid, cholesterol and triglyceride contents in liver were significantly lower in EGP and EGC group than control group. Antioxidant activity in serum was the highest in EGC groups by 50.86%, in liver was the highest in EGP groups. TBARS content in serum and liver was the lowest in EGP group. In these results, we suggest that EGP composites could have hypolipidemic and anti-obesity effects in rats fed a high fat diet.
