ABSTRACT
Process of enzyme assisted extraction (EAE) of polysaccharides from Cornus officinalis was optimized by response surface methodology (RSM). The influence of four different factors on the yield of C. officinalis polysaccharides (COP) was studied. Results showed that the optimal conditions were compound enzyme amount of 2.15%, extraction pH of 4.2, extraction temperature of 55 °C and extraction time of 97 min. Under these conditions, the COP yield was 9.29±0.31%, which was well in agreement with the value predicted by the model. The three methods, EAE, hot water extraction (HWE), ultrasound-assisted extraction (UAE) for extracting COP by RSM were further compared. Results showed that EAE had the largest yield of polysaccharides with lower equipment cost.
