This study was performed to investigate the effect of Brassica rapa (BR) sprouts on weight reduction and cholesterol-lowering action in rats fed high fat diet for 4 weeks. Weight-matched male Sprague-Dawley rats were assigned to four groups according to dietary fat levels (10% or 20% of diet wt.). Experimental groups were normal diet group (N), high fat diet group (HF), high fat diet with 5% BR sprouts powder group (HF-BRL), and high fat diet with 10% BR sprouts powder group (HF-BRH). The body weight gain was increased in HF group, but gradually decreased to the corresponding level of the N group fed BR sprouts powder. The concentrations of serum LDL-cholesterol, atherogenic index and cardiac risk factor tended to decrease in the BR sprouts powder fed groups compared with the HF group. However, HDL-cholesterol concentration in serum decreased in the HF group and markedly increased in the BR sprouts powder fed groups. Concentrations of triglyceride and total cholesterol in liver were also markedly decreased in the BR sprouts powder fed groups. Triglyceride concentrations of epididymal and mesenteric adipose tissues in the BR sprouts powder fed groups were also decreased compared with the HF group. These results indicate that BR sprouts powder may reduce fat accumulation and body weight, and have cholesterol-lowering effect.
