Structural characterisation and antioxidant and prebiotic activities of Ophiopogon japonicus polysaccharides obtained by enzymatic pretreatment followed by simultaneous microwave–ultrasound-assisted extraction

In this study, response surface methodology was used to optimize a sequential two-stage process comprising enzymatic pretreatment followed by simultaneous microwave–ultrasound-assisted extraction of Ophiopogon japonicus polysaccharides. At the unrounded model optimum (208.492 W microwave power, 300.945 W ultrasonic pow...
