Nitrite Scavenging Activity of The Ethanol and Water Extracts Obtained from Hizikia fusiforme and Sargassum fulvellum

톳(Hizikia fusiforme)과 모자판(Sargassum fulvellum) 에탄올 및 물 추출물의 아질산염 소거작용

The purpose of this study was to investigate the nitrite scavenging activity of the ethanol and water extracts obtained from Hizikia fusiforme and Sargassum fulvelum using sodium nitrite under different pH conditions. The nitrite scavenging activity was appeared in all the extracts examined and it showed the highest value at pH 1.2 The ethanol extract of Hizikia fusiforme provided higher activity than the water extract of that. Ohterwise, the nitrite scavenging activity of Sargassum fulvelum ethanol extract was similar to that Sargassum fulvelum water extract. There was significant difference among concentration of extracts Hizikia fusiforme and Sargassum fulvelum. Also, nitrite scavenging activity of the extracts Hizikia fusiforme and Sargassum fulvelum decreased with higher pH condition. In addition, the activity was increaed with higher concentration of extracts Hizikia fusiforme and Sargassum fulvelum in the course of reaction time 30 minute to 3 hour.
