Abstract

This study was performed to verify the effects of corn husk powder on serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. Powder of corn husks has been used as a folk remedy from ancient times in Korea. In the case of corn husk measurement of TPC (p<0.05), ABTS+ radical scavenging activity of trolox (p<0.05), DPPH radical scavenging activity (p<0.05), and measured value of FRAP (p<0.0001) were higher in ethanol extract than water extract. Weight of livers was significantly higher in the control group and high-fat diet group compared to groups fed 10% and 20% corn husk powders with high-fat diet (p<0.0001). For blood HDL-cholesterol concentration, mice fed 10% corn husk powder with high-fat diet ($160.00{\pm}16.17mg/dL$) showed significantly higher levels compared with the other three groups (p<0.05). Mice fed 10% and 20% corn husk powders with high-fat diet showed high numerical values of $13.50{\pm}2.51$ and $11.25{\pm}2.87mg/dL$, respectively. For triglyceride concentration in blood, mice fed 10% ($83.50{\pm}19.30mg/dL$) and 20% ($88.50{\pm}22.25$) corn husk powder with high-fat diet showed very low levels compared to the control group and high-fat diet group. In the case of leptin, the high-fat diet group showed a significantly high level of $5.88{\pm}3.53ng/dL$. Groups fed 10% and 20% corn husks with high-fat diet showed low numerical values of $2.72{\pm}2.34ng/dL$ and $1.10{\pm}0.62ng/dL$, respectively (p<0.05). Corn husk powder increased high HDL-cholesterol concentration in blood while lowering triglyceride concentration and leptin secretion. Therefore, powder of corn husks has utility in the food industry and food processing.
