Comparisons of Nutritional Components and Antioxidative Effects of Korean and Chineses Agrimonia pilosa Ledeb. Yang Da-Hyun Advisor : Prof. Lee, Jae-Joon, Ph. D. Major in Nutrition Education Graduate School of Education, Chosun University This study compared the effects of Korean Agrimonia pilosa Ledeb.(L.) powder and Chinese Agrimonia pilosa L. powder on their nutritional components and antioxidative effects. The crude fat contents of Korean Agrimonia pilosa powder L. were higher than those of Chinese Agrimonia pilosa L. powder. There were no significant differences in the contents of moisture, crude protein, crude ash, and carbohydrates between Korean Agrimonia pilosa L. powder and Chinese Agrimonia pilosa L. powder. The total amino acid contents were in the order of aspartic acid, glutamic acid, and leucine for both Korean and Chinese products. The total saturated fatty acid contents of Chinese Agrimonia pilosa powder L. were higher than those of Korean Agrimonia pilosa L. powder, while the contents of monosaturated fatty acid polyunsaturated fatty acid were higher in Korean Agrimonia pilosa L. powder. In the case of organic acids, Korean Agrimonia pilosa L. powder were detected in the order of malic acid, tartatic acid, citric acid, acetic acid, and formic acid, while Chinese Agrimonia pilosa L. powder were detected in the order of tartaric acid, malic acid, citric acid, formic acid, lactic acid, and acetic acid. As a result of analyzing the mineral content of Korean Agrimonia pilosa L. and Chinese Agrimonia pilosa L., both were found to have a high potassium content. The total polyphenol content of ethanol extracts of Korean and Chinese Agrimonia pilosa L. powders was found to contain 190.48 mg GAE/g and 182.44 mg GAE/g, respectively. The total flavonoid was also found to contain 445.33 mg QE/g of Korean Agrimonia pilosa L. and 242.90 mg QE/g of Chinese Agrimonia pilosa L. When comparing the DPPH radical erasing ability and the ABTS radical erasing ability, Korean Agrimonia pilosa were measured higher than Chinese Agrimonia pilosa L. at all concentrations. In conclusion, these results indicate that Korean Agrimonia pilosa L. powder are slightly better at preserving nutritional and antioxidant activity compared to Chinese Agrimonia pilosa L. powder. Furthermore, these results may provide basic data for future studies for a better understanding of the functional activity of Agrimonia pilosa L. powder.
