Abstract
The purpose of this study was to investigate whether water extracts of Sparassis crispa (SC) have anti-obesity effects. Treatment of mature adipocytes with SC caused a decrease in lipid accumulation (assessed by Oil Red O staining) and an increase in glycerol release. Mice were induced to obesity by a high fat diet (45% fat in total kcal) and experimental groups were treated with two different dosages of SC extracts, a low SC (LSC, 100 mg/kg/day) or high SC (HSC, 300 mg/kg/day). SC extracts were administered by gavages for 10 weeks in the experimental groups, while the control group was fed with distilled water. The body weight gain of mice fed SC was significantly reduced (11.88% lower in LSC, 14.54% lower in HSC) compared to the control group. Additionally, there were significantly reduced serum levels of triglycerides (13.57% lower in LSC, 19.46% lower in HSC), total cholesterol (32.22% lower in LSC, 24.67% lower in HSC) and glucose (28.85% lower in LSC, 25.82% lower in HSC) in mice fed SC compared to the control group. Hepatic triglycerides in mice fed SC were lower (9.68% lower in LSC, 14.24% lower in HSC) than the control group and total cholesterol levels were also lower in mice fed SC (38.72% lower in LSC, 35.20% in HSC). These results demonstrate that the water extract of SC may enhance lipolysis and up-regulate the expression of lipolytic enzymes in vitro and reduce body weight in vivo. These significant effects were found for both low and high doses of SC treatment, and suggest SC can be used as potential therapeutic substances for the prevention and treatment of obesity.
