摘要
利用超声波辅助提取木棉[Gossampinus malabarica(Dc.)Merr.]花多糖,先考察了不同料液比、超声波功率、提取时间、提取温度和提取次数对木棉花多糖提取率的影响,然后利用正交试验优化木棉花多糖的提取工艺,并对结果进行分析。结果显示,木棉花多糖最佳提取工艺参数为,料水质量比1∶60、提取温度60℃、超声波功率250W、提取时间20 min、提取2次。
Polysaccharide was extracted from Bombax[Gossampinus malabarica （Dc.） Merr.] flower by ultrasonic assisted extraction method. The effects of some physical and chemical factors, such as solid-solvent ratio, ultrasonic temperature, ultra- sonic power and ultrasonic time, on the extraction yield were investigated. According to orthogonal design, the optimum con- ditions for the extraction of polysaccharide were as follows, solid-solvent ratio, 1：60 （m/V,g：mL）; Ultrasonic temperature, 60 ℃; Ultrasonic power, 250 W; Ultrasonic for 20 min twice.
