Objectives : To find out more pharmacologically efficient way of extraction of herbal dicoction, Gamichungsangbohatang (GMCSBHT). Methods : Several main components of GMCSBHT was compared and analysed between hot water extract of GMCSBHT and Alcohol(70% ethanol) extract of GMCSBHT via HPLC method. Results : Hot water extract of GMCSBHT showed relatively more component content than ethanol extract of GMCSBHT. Also weighted mean of main components of hot water extraction of GMCSBHT was higher than that of alcohol extract of GMCSBHT. But from chromatographic pattern analysis of matching ratio and similarity ratio showed that these two forms of extracts might have different chemical composition, and 3D PDA plot of alcohol extract of GMCSBHT showed high peaks near UV $190{\sim}220nm$ which was invisible in hot water extract of GMCSBHT. Conclusion : Alcohol extract of GMCSBHT may have some special components which do not exist in hot water extract of GMCSBHT.
