초임계추출법을 이용하여 향유로부터 정유물질을 추출하여 향기성분과 항산화물질을 최대로 추출할 수 있는 최적조건을 반응표면 분석법으로 얻고자 하였다. 추출물의 품질특성으로는 yield, total phenolics, electron donating ability 등을 분석하였으며 주요 향기성분으로는 estrgole과 L-carvone을 선정하였다. 반응변수들은 추출시간보다는 온도의 변화에 따라 비례적으로 증가하는 경향을 보였으며, 측정된 변수에 대하

This study was performed to develop flavor materials from Elsholtzia ciliata Hylander with analyzing functionality and aroma profile and to optimize supercritical fluid extraction method and optimum condition. The qualities of water extracts such as total yield total phenolic compound electron donation ability, estragole and L-carvone, were affected by extraction pressure than time. The response variables had significant with pressure than with time and the established polynomial model was suitable(P>0.05) model by Lack-of-Fit analysis. The optimum extraction conditions which were limited of maximum value for dependent variables under experimental conditions based on central composite design were 238 bar and 42 min.
