Cellulase-assisted extraction, characterization, and bioactivity of polysaccharides from Polygonatum odoratum

Cellulase-assisted extraction of polysaccharides from Polygonatum odoratum (CPP) was optimized by response surface methodology (RSM) and the extracted CPP's preliminary chemical characteristics, as well as antioxidant and immunomodulatory activities were also investigated. The optimal extraction parameters comprised an extraction temperature of 58.21 °C, an extraction time of 3.18 h, pH value of 5.8, and cellulase amount of 6.0%. Under these...
