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·m L- 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 · m L- 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.
