Abstract

The stem bark of Kalopanax pictus was extracted with ethanol and water. Total phenolic compounds, crude saponins and electron donating abilities of the extracts were the highest in water extract treated at $70^{\circ}C$ for 8 hr. Response surface methodology (RSM) was used to monitor the characteristics of extracts from Kalopanax pictus. A central composite design was applied to investigate the effects of the two independent variables, extraction temperature ($X_{1}$) and extraction time ($X_{2}$), on five dependent variables, soluble solid ($Y_{1}$), total phenols ($Y_{2}$), crude saponin ($Y_{3}$), electron donating ability ($Y_{4}$), and reducing sugar ($Y_{5}$), of the extracts. Soluble solids increased in proportion to extraction temperature and time, but did not increase after the extraction condition of approximately $77^{\circ}C$ and 6.8 hr. As the extraction time increased, total phenolic compounds and reducing sugar contents increased. Extraction temperature played a minor role. The optimum range of extraction conditions for maximized physicochemical properties were $86-94^{\circ}C$ and 6.00-7.48hr. The agreement of the predicted values at the optimized conditions with the experimental values was acceptable.
