본 연구는 국내산과 중국산 엉겅퀴(전초, 뿌리)의 일반성분과 항산화 활성을 분석하였다. 수분 함량은 전초보다 뿌리에서 더 많았고, 국내산과 중국산의 함량은 비슷하였으며, 회분 함량은 국내산 엉겅퀴 전초에서 많았다. 단백질 함량은 국내산 전초와 중국산 뿌리에서 많았고, 지방 함량은 중국산 엉겅퀴에서 많았으며, 탄수화물 함량은 국내산 뿌리가 많았다. 칼륨 함량은 중국산 뿌리가 많았고, 칼슘, 마그네슘 함량은 국내산 전초가 제일 많았다. 인과 철 함량은 국내산 전초에서 많았다. 구리는 국내산 전초와 중국산 뿌리가 많았다. 비타민 A와 비타민 C는 검출되지 않았으며, 비타민 E와 $eta$-carotene은 국내산 전초에서 5.35 IU/100 g, 1,113.18 ${mu}g$/100 g을 검출되었다. 수율, 총 페놀과 총 플라보노이드 함량은 국내산 뿌리가 많았다. Sylimarin, cynarin, narirutin은 검출되지 않았으나 국내산 전초에서 apigenin이 확인 되었으며, 중국산 뿌리에서 acacetin이 검출되었다. 항산화성은 국내산, 중국산 엉겅퀴에서 낮았다. 따라서 국내산 전초가 영양성분이나 총 페놀, 플라보노이드, apigenin 함량이 많아 중국산이나 국내산 뿌리보다 더 우수하였다.
This study investigated chemical composition and antioxidant activity in the aerial parts or roots of Korean and Chinese Cirsium. Water was abundant in their roots than their aerial parts, and its content was similar between Korean Cirsium and Chinese one. Ash was abundant in the aerial parts of Korean one. Protein was abundant in the aerial parts of Korean one and the roots of Chinese one. Lipid content was abundant in the roots of Chinese one. Carbohydrate was abundant in the roots of Korean one while K content was abundant in the roots of Chinese one. Ca and Mg contents were abundant in the aerial parts of Korean one. P and Fe contents were abundant in the aerial parts of Korean one. Cu content was abundant in the aerial parts of Korean and Chinese ones. Vitamin A and vitamin C were not detected, but vitamin E and $eta$-carotene were contained 5.35 IU/100 g, 1113.18 ${mu}g$/100 g in the aerial parts of Korean one. Yield, total phenolics and total flavonoid contents were abundant in the roots of Korean one. Silymarin, cynarin, and narirutin were not detected in Korean and Chinese ones, but apigenin was identified in the aerial parts of Korean one. Acacetin was identified in the roots of Chinese one. Antioxidant activity was low in Korean and Chinese ones. These results suggest that nutrition composition, total phenolic content, total flavonoid content and apigenin content in the aerial parts of Korean Cirsium was superior than those in the roots of Korean and Chinese Cirsium.
