Abstract
Objectives : This study was performed to compare the differences between decoctions extracted by different extraction conditions. Methods : Two different decoctions were prepared with pressured or non-pressured extraction conditions for 60, 120 and 180min. The yields of extracts, sugar contents, hydrogen ion concentrations(pH), the contents of reference compounds and individual preferences on Ssanghwa-tang(Shuanghe-tang) were investigated. Results : As extraction time increased, individual preferences for decoctions by pressured extraction tended to increase more than those by non-pressured extraction, and the yields and sugar contents of both decoctions showed the tendency of increase. The pH values of decoctions in pressured conditions were lower than those in non-pressured conditions in all extraction times and both extraction conditions showed decreasing pH values according to increase of extraction times. Of the reference compounds, paeoniflorin showed higher contents in non-pressured conditions than in pressured conditions and the contents of cinnamaldehyde were always lower in non-pressured conditions than in pressured conditions at all time. Conclusions : The decoctions of Ssanghwa-tang(Shuanghe-tang) extracted by pressured or non-pressured extraction for 60, 120, 180min exhibited different individual preferences, yields of extracts, sugar contents, pH, reference compounds contents.
