Abstract

This study was conducted in order to establish the optimum extraction conditions in obtaining Saururus chinensis extracts. At the optimum extraction solvent (40% ethanol solvent), yield, DPPH, total phenolic compounds and total flavonoid in the extract of Saururus chinensis were 13.50%, 83.50%, 2.60 mg/ml and 2.09 mg/ml, respectively. At the optimum extraction time (4 hours), yield, DPPH, total phenolic compounds and total flavonoid in the extract of Saururus chinensis were 12.79%, 71.13%, 2.83 mg/ml and 2.16 mg/ml, respectively. At the optimum conditions (40% ethanol solvent and 4 hours), quercetrin and quercetin contents were 360.13 mg/100 g and 1379.54 mg/100 g, respectively. From the above results, we suggest that the optimum Saururus chinensis extract conditions are 40% ethanol solvent and 4 hours.

삼백초 지상부의 추출조건을 설정하고자 추출용매 및 시간에 따른 이화학적 특성을 살펴보았다. 추출용매 조건은 40% 에탄올을 사용하여 추출할 때로 나타났으며, 이때, 총수율, 전자공여능, 총페놀함량, 총플라보노이드 함량은 각각 13.50%, 83.50%, 2.60 mg/ml 및 2.09 mg/ml으로 나타났다. 최적의 추출 시간은 4시간으로 나타났으며, 이때, 총수율, 전자공여능,총폐놀함량, 총플라보노이드 함량은 각각 12.79%, 71.13%, 2.83 mg/ml 및 2.16 mg/ml으로 나타났다. 삼백초 지상부를 40% 에탄을 추출물로 4시간 추출하였을때, quercetin 함량은 360.13 mg/100 g으로 나타났으며, quercetin 함량은 1379.54 mg/100 g으로 나타났다. 삼백초 지상부를 이용하여 추출조건을 설정한 결과 40% 에탄올을 이용하여 4시간 추출하는 것이 가장 적합한 것으로 나타났다.
