- W2053461012 abstract "본 연구에서는 울금의 품종별 생리활성을 확인하기 위하여 우리나라에서 재배되고 있는 울금, 강황 및 보라울금의 근경을 실험재료로 하여 total polyphenol 함량, 항균활성, 항균물질의 열안정성 및 pH안정성과 항산화활성을 측정하였다. 울금 품종별 total polyphenol 함량은 울금과 강황에서 보라울금에 비하여 높은 함량을 나타내었다. 울금의 추출 용매에 따른 항균활성은 ethanol 추출물이 15.4~16.3 mm로 가장 강한 항균활성을 나타내었으며 ethylacetate, ether, hexane 순으로 높은 활성을 나타내었다. 품종별로는 울금 ethanol 추출물의 항균활성이 다른 품종에 비하여 높게 나타났으나 E coli와 젖산균 2종, 효모 2종에서는 항균활성이 나타나지 않았다. 울금 ethanol 추출물은 열 및 pH변화에 안정함을 확인하였다. 추출물별 울금의 전자공여능은 ethanol 추출물에서 74.2%로 높은 항산화성을 보였고 ethyl acetate, ether, water, hexane 추출물 순으로 나타났다. 품종별 울금의 전자공여능을 ethanol 추출물에서 비교했을 때 울금 74.2%, 강황 43.98%, 보라울금 43.05%로 나타나 울금에서 강한 항산화성을 보였다. 대조구로 사용한 vitamin C와 BHA는 각각 95%와 96.1%의 높은 전자공여능을 나타내었다. 울금 품종별 항산화성은 울금이 강황과 보라울금에 비하여 월등히 높음을 확인하였다. We investigated the antimicrobial and antioxidant activities. and total polyphenol contents of Curcuma longa. Curcuma aromatica. and Curcuma zedoaria. In antimicrobial activity assays of solvent extracts, ethanol extract showed the highest activity compared with other extracts. The antimicrobial activity of ethanol extract of C. longa showed higher than those of C. aromatica, and C. zedoaria. Antimicrobial substance in ethanol extract of C. longa was maintained after heating at <TEX>$100^{circ}C$</TEX> for 30 min and not affected by changes in pH. DPPH free radical scavenging activity of solvent extracts were high in the order of ethanol, ethylacetate, ether, water, and hexane fractions, C. longa showed greater DPPH free radical scavenging activity than those of the C. aromatica, and C. zedoaria. Total polyphenol content of C. longa and C. aromatica exhibited were similar levels, whereas C. zedoaria was slightly lower concentration." @default.
