Abstract:

Response surface methodology (RSM) based on a central composite design (CCD) was applied for the optimization of extraction process of crude polysaccharides from Schisandra chinensis (Turcz.) Baill. In RSM analysis, the pairwise interactive effects of solid/liquid ratio, extraction temperature and extraction time on the yield of crude polysaccharides were examined. Results showed that the optimal values of the above parameters were determined as follows: solid/liquid ratio 1:40 (m/V), extraction temperature 90.3 ℃, and extraction time 5 h. Under the optimized conditions, the experimental value of yield of crude polysaccharides was (10.994 ± 0.332)% and was in good agreement with the predicted value.

Key words: response surface methodology, Schisandra chinensis, polysaccharides, extraction
