Objective To optimize extraction of polysaccharides from Cortex Acanthopanacis. Method With the polysaccharides yield as indicators, single factor and orthogonal design were used to optimize extraction technology by solvent dosage, taking extraction times and extraction time as factors. Result Optimum extraction technology was as following: accurately weighed 10.0 g herbs, add water 200 mL,extracted 4 times at 90 min each time by ultrasonic extraction. Conclusion These optimized extraction and purification processes were stable and reliable, which indicated that optimized processes were suitable for industrial production of polysaccharides from Cortex Acanthopanacis.
