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.

Objectives: Three yin-tonifying formulae (Ssanghwa-tang, Yukmijihwang-tang and Jaeumganghwa-tang) were applied to investigate their immunological activities on antigen (Ag)-specific or Ag-non-specific immune responses in the murine macrophage cell line (RAW 264.7) and in ovalbumin (OVA)-immunized mice. Methods: This study was carried out in nitricoxide (NO) synthesis in RAW 264.7 cells and cellular proliferation in mouse splenocytes in association with three herbal formulas. C57BL/6 mice were immunized intraperitoneally with OVA/aluminum ($100\;{\mu}g/200\;{\mu}g$/mouse) on days 1, 8, and 15. Three herbal formulas were administrated to mice orally for 3 weeks from day 1. On day 22, OVA-, lipopolysaccharide (LPS)-, and concanavalin A (Con A)-stimulated splenocyte proliferation and antibodies (OVA-specific antibodies of the IgG, IgG1, and total IgM classes) in plasma were measured. Results: All three yin-tonifying formulas significantly enhanced cellular proliferation by LPS and Con A in splenocytes from OVA-immunized mice (p<0.001). Also, these herbal formulas all significantly enhanced plasma OVA-specific IgG, IgG1, and total IgM levels compared with the OVA/Alum group. Conclusion: These results suggested that the three yin-tonifying formulae could be used as stimulators of immune response.
