Abstract
|
|
|
|
Optimal extraction conditions were established from the difference of quality characteristics according to extraction conditions of Ssangwha extracts(SWE). Extract yields of SWE obtained from the established extraction conditions were as follows. The maximum yield was 48.90% at extraction temperature 90^{circ}C and alcohol concentration 50%, extraction yield and alcohol concentration of extraction solvent was proportioned. Increase of extraction yields at extraction temperature 80∼90^{circ}C and more than alcohol concentration 30% had slowdown tendency according to increase of alcohol concentration. At this view point, the optimum extraction conditions were alcohol concentration 30% and more than extraction temperature 80^{circ}C. In this study, optimal extraction conditions of SWE were extraction temperature 90^{circ}C and alcohol concentration 30%.
