안전한 천연물을 이용한 천연항산화제 개발 연구의 일환으로, 오크라, 엉컹퀴, 엄나무 및 줄풀 등 4종의 천연 약용식물 추출물의 항산화 활성을 측정해보았다. 추출물의 총 phenolic compounds 함량은 오크라와 엉컹퀴는 50% ethanol, 엄나무는 40% ethanol, 줄풀은 60% ethanol에서 최대용출을 나타내었으며, water 추출물에서 2.72~34.15 mg/g, ethanol 추출물에서 2.83~34.23 mg/g의 용출율을 나타내었다. 4종류 약용식물 water과 ethanol 추출물의 DPPH radical 소거능은
In this study, the antioxidant activity of water and ethanol extracts from Hibiscus esculentus, Cirsium japonicum, Zizania latifolia and Kalopanax pictus for functional food source were examined. The optimal conditions for phenolic compounds extraction from medicinal plants were at 50% ethanol with Hibiscus esculentus and Cirsium japonicum var. ussuriense, at 40% ethanol with Kalopanax pictus and at 60% ethanol with Zizania latifolia. The total phenolic contents from the extracts of medical plants were determined to be 2.72~34.15 mg/g in the water extracts and 2.83~34.23 mg/g in the ethanol extracts. The electron-donating abilities (EDA) of the water and ethanol extracts were both above 74% at the low concentration of
