摘  要:
目的:研究超声波辅助提取库拉索芦荟多糖的最佳工艺。方法:通过正交试验研究库拉索芦荟多糖的水浴提取工艺;通过单因素试验及正交试验研究超声波辅助提取库拉索芦荟多糖的提取工艺。结果:水浴提取库拉索芦荟多糖的最佳方法是:料液比1:6、水浴时间60mim、水浴温度65℃、浸提液的pH值为9.0。超声波辅助提取库拉索芦荟多糖的最佳试验方案为:料液比1:4、超声功率100W、超声时间为6min、浸提液的pH值为9.0。结论:得到了超声波辅助提取库拉索芦荟多糖的提取工艺,超声波辅助提取法显著优于水浴提取法。

摘  要:
The extractionl process of polysaccharides from Aloe vera L. was optimized by single factor test and orthogonal test in this study. The results showed that the optimal conditions for extracting polysaccharides from Aloe vera L. by hot water extraction method are as follows: material-liquid ratio 1:6,temperature 65℃,time 60 minutes,and pH 9.0. The optimal conditions for extracting polysaccharides from Aloe vera L. by ultrasonic-assisted extraction method are as follows: material-liquid ratio 1:4,ultrasonic power 100 W,pH 9.0,and time 6 minutes. The ultrasonic-assisted extraction method is better than the single hot water extraction method due to its much higher extraction rate.
