초록

In this study, we investigated the antioxidative activity (scavenging activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical and superoxide anion radical) and anti-obesity effects of black bean chungkugjang extract (BBCE). DPPH free radical-scavenging activity and superoxide anion radical-scavenging activity (SC50 value) of BBCE were 162.7±2.8 ppm, and 205.62±3.6 ppm, respectively. The anti-obesity effects of BBCE were investigated by measuring Oil Red O staining in 3T3-L1 adipocytes. BBCE reduced the content of Oil Red O dye in 3T3-L1 adipocytes. We also examined the effects of BBCE on adiposity, serum lipid, and leptin levels in obese mice fed a high-fat diet. Mice were fed the BBCE experimental diets for 7 weeks, after which they were sacrificed. ICR male mice were randomly divided into three groups, one normal diet group (ND group) and two high fat diet groups with or without BBCE supplementation (HFD group and HFD-BBCE group). The results showed that weight gain and the food efficiency ratio significantly decreased upon addition of BBCE compared to those of the HFD group. Further, white adipose tissue weights of epididymal, mesenteric, and retroperitoneal areas in the HFD-BBCE group were reduced to 34.8%, 7.1%, and 40.6%, respectively, compared to that of the HFD group. The serum levels of triglycerides, total cholesterol, LDL-cholesterol, and leptin in the HFD-BBCE group were significantly lower than those of the HFD group. Based on these results, it can be concluded that BBCE may have beneficial effects on reducing fat mass and serum lipid content.
