The extraction process optimization and physicochemical properties of polysaccharides from the roots of Euphorbia fischeriana
چکیده انگلیسی

Response surface methodology (RSM) was used to determine the optimum extraction conditions for polysaccharides (EFP) from the roots of Euphorbia fischeriana. A Box–Behnken design (BBD) with four independent variables was investigated, such as extraction temperature (°C), water/solid ratio, extraction number (n), and extraction time (h). The results indicated optimum extraction conditions were extraction temperature of 97 °C, water/solid ratio of 9:1, extraction number of 2 and extraction time of 2.4 h, respectively. Under these conditions, the experimental value was 24.6 ± 0.62, which was well in close agreement with value predicted by the model. The preliminary chemical analysis of EFP revealed the EFP contained 25.43% polysaccharides, 20.42% uronic acids, 2.54% sulfate radical and 23.41% proteins. And the neutral polysaccharides were mainly composed of glucose, arabinose, rhamnose, galactose, xylose, mannose in the ratio of 21:8:5:3:1:1.
