Effect of In Vitro Antioxidant Properties and Extract of Corn Husk on Serum Lipids in Mice

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.
