Abstract
Considering the thermal unstableness of ginseng components, microwave-assisted extraction(MAE) was performed under the atmospheric pressure condition. The monitoring of extraction characteristics and the optimization of extraction conditions were made by response surface methodology. The extraction efficiency of soluble ginseng components was high at lower ethanol concentration and at higher microwave power, while crude saponin content was easily extracted at higher ethanol concentration. Estimated conditions for the maximized extraction of soluble components including crude saponin, total phenolics and electron donating ability were
인삼 성분의 열불안정성과 실용성을 고려하여 상압 조건에서 마이크로웨이브 추출실험을 실시하면서 반응 표면분석에 의해 추출조건의 최적화 및 추출특성을 모니터링하였다. 가용성 성분의 수율은 에탄올 농도가 낮고 microwave power가 높을수록, 조사포닌 함량은 에탄올 농도가 높을수록 증가하였다. 그리고 추출물의 가용성성분 함량, 조사포닌 함량, 페놀성화합물 함량, 전자공여작용 등의 추출물 특성을 모두 만족시키는 최적 추출조건을 예측하여 보았을 때, 에탄올 농도
