Abstract
The purpose of this study was to investigate the one way ethanol concentrations, time, temperature and the ratio of material/solvent extraction, which affected the extraction process of flavonoids from Ampelopsis cantonensis, resulting in 70%; 90 minutes; 80°C; 1/15 (w/v). On the basis of the factors affecting the extraction conditions, we found that the solvent concentration, extraction time and extraction temperature strongly influence the extraction process. Application of Box-Behnken design found the optimal condition for the extraction process of Ampelopsis cantonensis with ethanol at concentration of 69.72%, extraction time 92.75 minute, extraction temperature of 79.88°C, which created the amount of flavonoids of 17.53%. Experimental results showed high degree of compatibility with the model.
