Study on Microwave-Assisted Extraction of Polysaccharides from Radix astragali

Abstract:

In this study, microwave-assisted extraction (MAE) was employed for the extraction of polysaccharides from Radix Astragali (PRA). The extraction parameters that influenced the extraction yield of PRA were optimized by orthogonal test design. The results showed that the optimal MAE conditions were as followings: liquid-solid ratio of 18 ml/g, irradiation time of 8 min, irradiation power of 300 W and extraction temperature of 65°C, while extraction yield of PRA was 8.39 %. The developed MAE method provided a good alternative for the extraction of PRA.
