Response surface methodology was used to optimize the extraction conditions of water-soluble polysaccharides from Stachys sieboldii Miq. tubers. A central composite design was used to optimize the extraction processing parameters. The optimum extraction conditions are as follows: extraction temperature, 95°C; extraction time, 2.5h; water to raw material ratio, 16; and extraction frequency, 3. Under the optimized conditions, an experimental yield of 9.21 ± 0.18%, which is in good agreement with… CONTINUE READING
