摘　　要：以兰州百合废弃鳞茎为原料,通过正交试验对超声波辅助提取兰州百合多糖的工艺进行优化,并考察了兰州百合多糖的稳定性。结果表明:超声波辅助提取兰州百合多糖的最佳工艺条件为料液比1:20(g/mL),超声时间60min,超声温度60℃,超声功率250W,该条件下兰州百合多糖提取率为18.44%。多糖提取物抗氧化性较差,易被H_2O_2氧化,但具有良好的抗还原性。An orthogonal test was utilized to optimize the ultrasonic-assisted extraction process of polysaccharides from Lilium davidii var waste bulb,and the stability of the polysaccharides was studied.The results showed that the optimum extraction conditions for ultrasonic-assisted extraction process were as followed:the ratio solid to liquid of 120(g/mL),ultrasonic time of 60 min,ultrasonic power 250 W,and ultrasonic temperature 60℃.Under the conditions,the extracting rate of polysaccharides from Lilium davidii var was 18.44%.The anti-oxidization stability of polysaccharide extracts was poor,whicht was easy to be oxidized by H 2O 2,but has good anti-reduction ability.
