Abstract: We investigated polysaccharide extraction yield from peony seed pods by single-factor experiments with water extraction method under extraction temperature of 40-100℃, extraction time of 15-240 min and solidliquid ratio of 1∶5-1∶40 g·mL-1. Under the optimum extraction process of orthogonal test, extraction temperature of 100℃, extraction time of 60 min and solidliquid ratio of 1∶15 g·mL-1, the polysaccharide extraction yield reached to 8.34%. Water extraction method has the advantages of the simple process, no environmental pollution and no solvent recovery problem. Our results can provide the experimental evidences for peony seed pod utilization.
