ABSTRACT
<p><b>OBJECTIVE</b>To optimize the process of extracting effective constituents from lotus leaf.</p><p><b>METHOD</b>Independent variables were ethanol concentration reflux time and solvent fold, dependent variables were extraction rates of nuciferine and flavone in lotus leaf, central composite design and response surface methodology were used for optimization of extraction of lotus leaf.</p><p><b>RESULT</b>The optimum conditions of extraction process were 75% -80% ethanol, 2-3 hours for reflux, 20-25 fold solvent and 2 times for extraction. Bias between observed and predicted of rates of nuciferine and flavone values were 5.53%, -6.02%, respectively.</p><p><b>CONCLUSION</b>The values observed and predicted were close to each other, which proved that the optimization of of extraction of lotus leaf by central composite design and response surface methodology was reasonable and successful.</p>
