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—240min)和料液比(1:5—1:40g·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60min,料液比1:15g·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。
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 rain 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.
