摘要: 采用热水浸提法提取决明子水溶性多糖。选择浸提时间、温度、浸提固液比以及提取次数作为单因素进行梯度实验,确定其条件范围,再通过进一步的正交实验得到决明子水溶性多糖浸提工艺的优选因素组合:浸提时间2.5h,温度80℃,固液比为1:30,反复浸提两次。

Abstract: The hot water extraction of the water-soluble polysaccharides from Cassia seeds was studied.The effects of four factors such as the temperature of extraction,the proportion of water volume,the time of extraction,the number of extractions on the extraction of the water-soluble polyccharides were investigated.with the orthogonal design of L9(34),the optimum conditions of extraction were obtained as follows:adding 30 times water as much as Cassia in 80℃ for 2.5 hours by 2 times extraction.
