Abstract

본 연구는 찔레의 열수추출물과 에탄올추출물간의 항산화 활성 비교를 위해 in vitro에서 총 페놀 및 플라보노이드 함량을 측정하였으며, DPPH, ABTS, NO radical 소거능 및 환원력을 $10{\sim}500{\mu}g/ml$ 의 농도에서 실험하였다. DPPH radical 소거능은 열수추출물(4.95~92.15%)과 에탄올추출물(2.76~90.55%)이 모두 농도 의존적으로 유의성 있게 높아졌으며 열수추출물이 더 높은 소거능을 보였다. ABTS radical 소거능을 비교한 결과 열수추출물(4.44~92.99%)이 에탄올추출물(2.63~87.12%)에 비해 유의적으로 높은 소거활성을 나타내었다. 환원력은 열수추출물(0.256~0.775)이 에탄올추출물(0.234~0.568)에 비해 유의적으로 높은 활성을, 그리고 농도 의존적으로 높아지는 것을 보였으며, NO radical 소거능을 비교한 결과 열수추출물이 에탄올추출물보다 조금 높은 활성을 보였고 농도 의존적으로 높아지는 것을 확인하였다. 찔레추출물의 항산화력의 $IC_{50}$ 값을 비교한 결과 DPPH radical 소거능, ABTS radical 소거능에서 각각 열수추출물에서 79.73, $79.82{\mu}g/ml$ 으로 나타났고, 에탄올추출물의 경우 145.85, $159.03{\mu}g/ml$ 로 나타났다. 총 페놀함량은 열수추출물에서 140.74 mg/g, 에탄올추출물에서 37.83 mg/g 플라보노이드 함량은 열수추출물에서 45.31 mg/g, 에탄올추출물에서 42.68 mg/g로 에탄올 추출물에 비해 열수추출물이 높게 나타났다. 결론적으로 찔레꽃 추출물은 항산화 효능을 나타내는 실험들에서 모두 높은 수치를 나타내어 천연 항산화제로 이용가치가 높다고 사료된다. This study was attempted to investigate antioxidant activities of water and ethanol extract from Rosa multiflora (RM) by in vitro assays measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, 2,2'-azino-di-2-ethyl-benzthiazoline sulphonate (ABTS) radical scavenging activity, reducing power activity, nitric oxide (NO) radical scavenging activity, total phenol and total flavonoid content. The water and ethanol extracts from RM scavenged the DPPH radical and ABTS radical in a dose-dependent manner at the concentration range from 10 to $500{\mu}g/ml$ . The DPPH radical scavenging activity of water extract was higher than that of ethanol extract. $IC_{50}$ of DPPH radical scavenging activity of water and ethanol extract were $79.73{\mu}g/ml$ and $145.85{\mu}g/ml$ . The reducing power activity of water extract was higher than that of ethanol extract. The nitric oxide (NO) radical scavenging activity of the RM extract was similar to their DPPH radical scavenging activity. $IC_{50}$ of ABTs radical scavenging activity of water and ethanol extract was $79.82{\mu}g/ml$ and $159.03{\mu}g/ml$ . The reducing power activity of water extract (0.775) was higher than that of ethanol extract (0.568). Total phenolic content of water extract (140.74 mg/g) was higher than that of the ethanol extracts (37.83 mg/g). Total flavonoid content of water extract (45.31 mg/g) was higher than that of the ethanol extracts (42.68 mg/g). This results suggest that water extract of RM may be useful as potential antioxidant sources.
