新疆阿拉套番红花球茎多糖的提取工艺研究

Study on extraction Process of Polysaccharides in Bulb of Crocus Alatavicus

采用超声波辅助的方法研究新疆阿拉套番红花球茎多糖的提取工艺.在单因素试验的基础上考察液料比、超声时间、温度、功率对多糖提取率的影响,结合正交试验法对多糖提取工艺进行优化.结果表明:最佳提取工艺条件为液料比57.5∶1(m L/g),超声时间40 min,超声温度80℃,超声功率400 W.该工艺条件下,新疆阿拉套番红花球茎多糖的平均提取率为74.4 mg/g.

Polysaccharides was extracted from bulb of Crocus alatavicus, based on single factor experiments. Or- thogonal experiments were used to determine the optimum extraction conditions. The optimal extraction conditions were obtained as follows： liquid feed ratio 57.5 ： 1 （mL/g）, ultrasonic time 40 min, extraction temperature 80℃ and ultrasonic power 400 W. Under this condition, the average extraction yield of polysaccharides was 74.4 mg/g.
