研究了超声波方法和传统方法对提取细叶百合鳞茎中多酚类物质的影响,同时对影响超声波提取细叶百合鳞茎中多酚类物质含量的多个因素进行正交试验分析。结果表明,超声波提取多酚类物质效果较好。超声波法提取的最佳方法条件为:100%甲醇,超声功率60 Hz,料液比1︰15(g/mL),pH 5,在50℃下超声提取40 min,连续提取2次,多酚类物质的总提取率可达到95.43%。
The effects of ultrasonic method and traditional method on the extraction of polyphenols from the bulb of Lilium orientalis were studied. The orthogonal test was conducted on the factors that affect the extraction of polyphenols from the bulb. The results show that ultrasonic extraction of polyphenols better. The optimum conditions of ultrasonic extraction were: 100% methanol, ultrasonic power 60 Hz, solid-liquid ratio 1︰15 (g / mL), pH 5, ultrasonic extraction at 50 ℃ for 40 min, The total extraction rate of substances can reach 95.43%.
