This study was conducted to verify the effects of Erigeron annuus powder on serum lipid levels of high-fat diet-induced mice from a nutritional viewpoint. Erigeron annuus powder has been used as a folk remedy since ancient times in Korea. There was no significant difference in the weight of the kidneys and spleens of the mice. The high-fat diet group had a significantly higher kidney weight compared to other groups (p<0.05). In the group of mice fed 20% Erigeron annuus powder with a high-fat diet, the concentration of serum LDL-cholesterol was high (p<0.05), whereas the concentration of triglyceride was remarkably lower compared to other groups (p<0.05). The group fed 10% Erigeron annuus with a high-fat diet had the lowest concentration of blood phospholipids (p<0.05) as well as the highest alkaline phosphatase and alanine aminotransferase levels in blood (p<0.05). There was no difference in blood insulin concentration. However, blood leptin concentration was significantly higher (5.88±3.53 ng/dL) in mice fed a high-fat diet compared to other groups (p<0.05). Measurements of Erigeron annuus revealed that TPC, ABTS+ radical scavenging activity of trolox, DPPH radical scavenging activity, and the measured value of FRAP were higher in the ethanol extract than in the water extract. Especially, the antioxidant activity effects were excellent for the ABTS+ radical scavenging activities of trolox and FRAP values of Erigeron annuus. Therefore, Erigeron annuus powder showed antioxidant activity. Hence, Erigeron annuus powder drastically lessened triglyceride concentration in blood in high-fat diet-induced mice. Thus, the powder is considered to have utility in the food processing industry. Additional related experiments are ongoing.
