摘要: 以牡丹种荚作为原料,水为提取溶剂,先采用单因素实验方法探讨提取温度(40~100℃)、提取时间(15~240 min)和料液比(1∶5~1∶40 g·mL-1)对牡丹种荚多糖提取率的影响,并通过正交实验优化工艺条件,确定最优提取工艺为:提取温度100℃,提取时间60 min,料液比1∶15 g·mL-1。此条件下,牡丹种荚多糖提取率为8.34%。水提牡丹种荚多糖,方法简单,无环境污染和溶剂回收问题,本文为牡丹种荚综合开发利用提供实验依据。

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.
