부위별 고려엉겅퀴(Cirsium setidens Nakai)의이화학적 성상 및 항산화 활성 효과

초록

In the present study, we investigated the compositions including protein, lipid, ash, carbohydrate, and minerals as well as antioxidant activity of Cirsium setidens Nakai in order to detect the biological activities and develop novel functional resources. Different organs commonly had the highest concentration of potassium among 7 minerals evaluated in this study. The leaf had K at the concentration of 5371.97 mg/100 g, while the flower, the stem, the root and the boiled leaf at the concentration of 1770.62 mg/100 g, 1983 mg/100 g, 6096.74 mg/100 g and 1604.2 mg/100 g, respectively. The monosaccharides were composed of the xylose, galactose and glucose. The xylose was only detected in the flower and stem and the galactose was only detected in the stem. DPPH scavenging activity was measured at the 88.22 μg/mL and 111.19 μg/mL in root and leaf at IC50 value in ethanol extracts, while 53.27 μg/mL, 75.84 μg/mL and 257.48 μg/mL in flower, boiled leaf and stem at IC50 value, respectively, in water extracts. These results suggest that extracts from Cirsium setidens Nakai can be potentially used as novel resources for antioxidant and biological active substances.
