Abstract: 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.
