The three independent variables are raw material drying temperature, extraction temperature, and extraction time. The dependent variables are both yield percentage of crude extract and total phenolic quantification as gallic acid equivalent in crude extract. The experimental design was based on central composite design. Highest yield percentage of crude extract could get from extraction condition at raw material drying temperature at 60&amp;deg;C, extraction temperature at 15&amp;deg;C, and extraction time for 25 min &amp;deg;C. Moreover, the crude extract with highest phenolic occurred by extraction condition of raw material drying temperature at 60&amp;deg;C, extraction temperature at 35 &amp;deg;C, and extraction lasting 25 min.</abstract> <index>Open Science Index 46, 2010</index> </article>
