| Abstract: | Microwave-assisted aqueous two-phase extraction of total saponins in Dioscorea Zingiberensis was studied by ethanol-dipotassium hydrogen phosphate system.The influence of extraction conditions on the extraction efficiency of the total saponins was investigated by orthogonal experiment.The results showed that the optimal extraction conditions were： the particle size of Dioscorea Zingiberensis was 80 mesh,microwave power was 390 W and microwave irradiation time was 5 min.Under the optimal conditions,the extraction efficiency of the total saponins was up to 13.32%. |
