Optimization of microwave-assisted extraction of polysaccharides from aloe peels by response surface analysis and its antioxidant activity

The study focused on microwave-assisted extraction of polysaccharides from aloe peels by response surface methodology, and the antioxidant activity of polysaccharides from aloe peels was also evaluated. The extraction conditions of microwave-assisted of polysaccharides from Aloe peels were optimized by response surface methodology, its mathematical model was established, moreover, its antioxidant activity was also studied in vitro. Results showed that the optimal parameiers of microwave extraction were liquid-solid ratio of 31:1 (mL/g), microwave time 95 s, microwave power 400 W, extraction temperature 74℃. Under the optimal conditions, the polysaccharide extraction rate was 4.926%. The antioxidant activity of polysaccharides from aloe peels was found in does dependent manner. © 2016, Editorial Office of Journal of CIFST. All right reserved.
