Abstract
In this paper, optimum extraction condition for berberine which is the indan companent of Coptidis rhizoma was examined at various conditions in the aspect of temperature, solvent and time followed by quantitation with reversed phase HPLC. The efficiency for extraction has been shown the best at <TEX>$60^{\circ}C$</TEX> with 2~3 hours reflux time in methanol or acetic acid. Any significant effect can not be shown from the addition of SLS to extraction solvent.
